Book excerpt: Advances in electronics have pushed mankind to create devices, ranging from - credible gadgets to medical equipment to spacecraft instruments. More than that, modern society is getting used to—if not dependent on—the comfort, solutions, and astonishing amount of information brought by these devices. One ?eld that has continuously bene?tted from those advances is the radio frequency integrated c- cuit (RFIC) design, which in its turn has promoted countless bene?ts to the mankind as a payback. Wireless communications is one prominent example of what the - vances in electronics have enabled and their consequences to our daily life. How could anyone back in the eighties think of the possibilities opened by the wireless local area networks (WLANs) that can be found today in a host of places, such as public libraries, coffee shops, trains, to name just a few? How can a youngster, who lives this true WLAN experience nowadays, imagine a world without it? This book dealswith the design oflinearCMOS RF PowerAmpli?ers(PAs). The RF PA is a very important part of the RF transceiver, the device that enables wireless communications. Two important aspects that are key to keep the advances in RF PA design at an accelerate pace are treated: ef?ciency enhancement and frequen- tunable capability. For this purpose, the design of two different integrated circuits realizedina0. 11μmtechnologyispresented,eachoneaddressingadifferentaspect. With respect to ef?ciency enhancement, the design of a dynamic supply RF power ampli?er is treated, making up the material of Chaps. 2 to 4.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a completely novel architecture that can relax the trade-off existing today between noise, power and area consumption in a very suitable solution for advanced wireless communication systems. Through the combination of charge-domain operation with incremental signaling, this architecture gives the best of both worlds, providing the reduced area and high portability of digital-intensive architectures with an improved out-of-band noise performance given by intrinsic noise filtering capabilities. Readers will be enabled to design higher performance radio front-ends that consume less power and area, especially with respect to the transmitter and power amplifier designs, considered by many the “battery killers” on most mobile devices.

Book excerpt: A current steering DAC-based average power tracking circuit for on-chip power amplifiers (PA) 3) A CMOS-based driver stage for GaN-based switched-mode power amplifiers applicable to fully digital transmitters This thesis highlights the trends in wireless handsets, the motivates the need for fully-integrated CMOS power amplifier solutions and presents the three novel techniques for reconfigurable and digital CMOS-based PAs. Chapter 3, presents the transformer-based power combiner for out-phasing transmitters. The simulation results reveal that this technique is able to shrink the power combiner area, which is one of the largest parts of the transmitter, by about 50% and as a result, enhances the output power density by 3dB. The average power tracking technique (APT) integrated with an on-chip CMOS-based power amplifier is explained in Chapter 4. This system is able to achieve up to 32dBm saturated output power with a linear power gain of 20dB in a 45nm CMOS SOI process. The maximum efficiency improvement is about [delta][eta]=15% compared to the same PA without APT. Measurement results show that the proposed method is able to amplify an enhanced-EDGE modulated input signal with a data rate of 70.83kb/sec and generate more than 27dBm of average output power with EVM

This book was released on 2006-02-08 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on high performance radio frequency integrated circuits (RF IC) design in CMOS. 1. Development of radio frequency ICs Wireless communications has been advancing rapidly in the past two decades. Many high performance systems have been developed, such as cellular systems (AMPS, GSM, TDMA, CDMA, W-CDMA, etc. ), GPS system (global po- tioning system) and WLAN (wireless local area network) systems. The rapid growth of VLSI technology in both digital circuits and analog circuits provides benefits for wireless communication systems. Twenty years ago not many p- ple could imagine millions of transistors in a single chip or a complete radio for size of a penny. Now not only complete radios have been put in a single chip, but also more and more functions have been realized by a single chip and at a much lower price. A radio transmits and receives electro-magnetic signals through the air. The signals are usually transmitted on high frequency carriers. For example, a t- ical voice signal requires only 30 Kilohertz bandwidth. When it is transmitted by a FM radio station, it is often carried by a frequency in the range of tens of megahertz to hundreds of megahertz. Usually a radio is categorized by its carrier frequency, such as 900 MHz radio or 5 GHz radio. In general, the higher the carrier frequency, the better the directivity, but the more difficult the radio design.

This book was released on 2010 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the design of CMOS power amplifiers for modern wireless handsets, where stringent linearity requirements and high power efficiency are difficult to achieve simultaneously. CMOS technology has been an attractive technology for research in fully-integrated transceivers due to its low cost and high-integration capability, as well as its continuously improving high-frequency performance. Its advantages, however, come at the cost of continuously reduced breakdown voltages, low isolation and high power loss in the substrate. To address these limitations, a stacked-FET design technique is first developed to systematically divide the voltage stress among several transistors connected in series, allowing the use of a larger supply voltage. The voltage swing of each stacked device is added in phase to provide a larger output power to the load without the requirement of a large impedance transformation. To investigate this technique, a fully-integrated 20 dBm RF power amplifier is first implemented using 0.25-[mu]m silicon-on-sapphire MOSFETs. By using triple-stacked FETs, the optimum load impedance for a 20 dBm power amplifier increases to 50 [Omega] so impedance transformation is not required at the output. Measurement of a single-stage linear power amplifier shows a small-signal gain of 17.1 dB and a saturated output power of 21.0 dBm with a power added efficiency (PAE) of 44.0% at 1.88 GHz. With an IS-95 code division multiple access (CDMA) modulated signal, the power amplifier shows average output power of 16.3 dBm and PAE of 18.7% with ACPR below -42 dBc. The concept is then further demonstrated at higher voltage and power level. A single-stage quadruple-stacked-FET linear power amplifier is presented using 0.28-[mu]m 2.5-V standard I/O FETs in a 0.13- & mu;m silicon-on-insulator (SOI) CMOS technology. The PA is designed to withstand up to 9 V of supply voltage before reaching its breakdown limit. The measured PA achieves a small-signal gain of 14.6 dB, a saturated output power of 32.4 dBm, and a PAE of 47% at 1.9 GHz with a 6.5-V supply. Using a reverse-link IS-95 CDMA modulated signal, the PA shows an average output power of up to 28.7 dBm with a PAE of 41.2% while meeting the adjacent channel power ratio requirement. The PA also shows an average output power of up to 29.4 dBm with a PAE of 41.4% while meeting the adjacent channel leakage ratio requirement of an uplink wideband code division multiple access (WCDMA) modulated signal. These performances are comparable to those of GaAs-based power amplifiers. To fully exploit the advantages of higher-speed CMOS technology and the availability of co-integrated digital circuitry, a digital-intensive transceiver architecture is explored as an alternative in the second part of the dissertation. A single-ended digitally-modulated power amplifier (DPA) is demonstrated in a 0.13-[mu]m 1.2-V SOI CMOS technology, to be used in a multi-standard RF polar transmitter. The amplitude modulation is done by digitally controlling the number of activated unit amplifiers whose currents are summed at the output. The DPA is designed for multi-mode multi-band functionality by avoiding frequency-selective components, except for the final-stage output matching network. The measured DPA delivers a 24.9-dBm peak output power at 900 MHz with a maximum power efficiency of 62.7%. Similar high-efficiency performance is also exhibited at 1.92 GHz with a reconfigured matching network. By employing a digital pre-distortion technique, the DPA could meet linearity requirements for both the enhanced data rate for GSM evolution (EDGE) and WCDMA standards.

This book was released on 2012 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high cut-off frequency of deep sub-micron CMOS technologies has enabled the integration of radio frequency (RF) transceivers with digital circuits. However, the challenging point is the integration of RF power amplifiers, mainly due to the low breakdown voltage of CMOS transistors. Silicon-on-insulator (SOI) metal semiconductor field effect transistors (MESFETs) have been introduced to remedy the limited headroom concern in CMOS technologies. The MESFETs presented in this thesis have been fabricated on different SOI-CMOS processes without making any change to the standard fabrication steps and offer 2-30 times higher breakdown voltage than the MOSFETs on the same process. This thesis explains the design steps of high efficiency and wideband RF transmitters using the proposed SOI-CMOS compatible MESFETs. This task involves DC and RF characterization of MESFET devices, along with providing a compact Spice model for simulation purposes. This thesis presents the design of several SOI-MESFET RF power amplifiers operating at 433, 900 and 1800 MHz with ~40% bandwidth. Measurement results show a peak power added efficiency (PAE) of 55% and a peak output power of 22.5 dBm. The RF-PAs were designed to operate in Class-AB mode to minimize the linearity degradation. Class-AB power amplifiers lead to poor power added efficiency, especially when fed with signals with high peak to average power ratio (PAPR) such as wideband code division multiple access (W-CDMA). Polar transmitters have been introduced to improve the efficiency of RF-PAs at backed-off powers. A MESFET based envelope tracking (ET) polar transmitter was designed and measured. A low drop-out voltage regulator (LDO) was used as the supply modulator of this polar transmitter. MESFETs are depletion mode devices; therefore, they can be configured in a source follower configuration to have better stability and higher bandwidth that MOSFET based LDOs. Measurement results show 350 MHz bandwidth while driving a 10 pF capacitive load. A novel polar transmitter is introduced in this thesis to alleviate some of the limitations associated with polar transmitters. The proposed architecture uses the backgate terminal of a partially depleted transistor on SOI process, which relaxes the bandwidth and efficiency requirements of the envelope amplifier in a polar transmitter. The measurement results of the proposed transmitter demonstrate more than three times PAE improvement at 6-dB backed-off output power, compared to the traditional RF transmitters.

This book was released on 2017 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power efficiency, bandwidth, and signal fidelity are critical specs of wireless transmitters, which are often traded off in transmitters with conventional analog circuit and antenna design. For example, high quality factor antennas and components help to achieve high efficiencies but often suffer bandwidth limitations. Switched-mode amplifiers and antennas have been proposed to achieve both high efficiency and broad bandwidth but the quantization noise issues prevent those techniques from being practically deployed. In this research, digitally enhanced techniques are proposed to enhance the design of switched-mode RF transmitter toward higher data rates, better power efficiency and lower quantization noise. Two specific research projects will be discussed. In the first project, an active noise filtering technique called Channelized Active Noise Elimination (CANE) is used to actively suppress the quantization noise in the bitstream modulated transmitter by employing the delaying and combining structure of multiple power amplification channels. The power efficiency of each of the power amplifier is preserved by a load modulation mechanism in the power combining operation. The proposed technique is implemented in a transmitter with a FPGA based signal processing module and the experimental results prove that the CANE technique can be a software-controlled, robust and flexibly tunable filter solution. The second project is utilizing the Direct Antenna Modulation (DAM) technique to surpass the physical bandwidth limit imposed by the high radiation quality factor of the electrically small antenna. The DAM concept has been proposed with various types of digital modulations, such as On/Off Keying, BPSK and QPSK, etc. A newly proposed DAM frequency shift keying (FSK) is developed to synthesize the parasitic components of switches with the matching circuit to improve the switching quality and signal integrity in the switched-mode electrically small antenna system.

Available in PDF, EPUB and Kindle. Book excerpt: With the explosive growth of the wireless market, the demand for low-cost and highly-integrated radio frequency (RF) transceiver has been increased. Keeping up with this trend, complimentary metal-oxide-semiconductor (CMOS) has been spotlighted by virtue of its superior characteristics. However, there are challenges in achieving this goal, especially designing the transmitter portion. The objective of this research is to demonstrate the feasibility of fully integrated CMOS transmitter module which includes power amplifier (PA) and transmit/receive (T/R) switch by compensating for the intrinsic drawbacks of CMOS technology. As an effort to overcome the challenges, the high-power handling T/R switches are introduced as the first part of this dissertation. The proposed differential switch topology and feed-forward capacitor helps reducing the voltage stress over the switch devices, enabling a linear power transmission. With the high-power T/R switches, a new transmitter front-end topology - differential PA and T/R switch topology with the multi-section PA output matching network - is also proposed. The multi-stage PA output matching network assists to relieve the voltage stress over the switch device even more, by providing a low switch operating impedance. By analyzing the power performance and efficiency of entire transmitter module, design methodology for the high-power handling and efficient transmitter module is established. Finally, the research in this dissertation provides low-cost, high-power handling, and efficient CMOS RF transmitter module for wireless applications.
