Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The improvement of high frequency capability for silicon devices has made implementation of millimeter-wave (mm-wave) silicon integrated circuits operating at 60 GHz, 77 GHz and even higher feasible. This had led to the proposal of a low-cost 77-GHz CMOS transceiver for automobile radar application and a 60-GHz wireless inter-chip interconnect system. This Ph. D work demonstrated an 80-GHz mm-wave receiver chain integrated with a frequency synthesizer fabricated using low leakage transistors of a low cost 65-nm bulk CMOS technology. An 80-GHz single-ended low noise amplifier (LNA), a 77-GHz down-conversion mixer and a 94-GHz voltage-controlled oscillator (VCO) have been separately demonstrated. A 1.2-V supply, the single-ended LNA exhibits 12-dB gain and 9-dB noise figure (NF) consuming 32- mW power. The mixer has -8-dB conversion gain and 17 dB NF while consuming only 6-mW power. With a 1.5 V supply, the VCO achieves 5.8% tuning range around 94 GHz and - 87dBc/Hz phase noise at 1 MHz offset while consuming 14-mW power. These designs demonstrate that the low-cost, low leakage CMOS process can be used for the design of mmwave circuit blocks and potentially larger integrated system despite the challenges of using the technology such as low voltage headroom, moderate metallization performance and strict metal density filling requirements.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract This chapter lays the foundation for the work presented in latter chapters. The potential of 60 GHz frequency bands for high data rate wireless transfer is discussed and promising applications are enlisted. Furthermore, the challenges related to 60 GHz IC design are presented and the chapter concludes with an outline of the book. Keywords Wireless communication 60 GHz Millimeter wave integrated circuit design Phase-locked loop CMOS Communication technology has revolutionized our way of living over the last century. Since Marconi’s transatlantic wireless experiment in 1901, there has been tremendous growth in wireless communication evolving from spark-gap telegraphy to today’s mobile phones equipped with Internet access and multimedia capabilities. The omnipresence of wireless communication can be observed in widespread use of cellular telephony, short-range communication through wireless local area networks and personal area networks, wireless sensors and many others. The frequency spectrum from 1 to 6 GHz accommodates the vast majority of current wireless standards and applications. Coupled with the availability of low cost radio frequency (RF) components and mature integrated circuit (IC) techn- ogies, rapid expansion and implementation of these systems is witnessed. The downside of this expansion is the resulting scarcity of available bandwidth and allowable transmit powers. In addition, stringent limitations on spectrum and energy emissions have been enforced by regulatory bodies to avoid interference between different wireless systems.

Available in PDF, EPUB and Kindle. Book excerpt: Broadband voltage-controlled oscillators are critical to the design of millimeter wave frequency synthesizers. This thesis proposes a design technique that can be used to significantly extend the achievable frequency span of an oscillator. A dual-band oscillator topology is described that can be configured to operate in one of two modes, by an electrical reconfiguration of the negative resistance core around the resonant tank, without switching passive elements within the tank itself. The configuration helps to minimize the difference in phase noise performance between the two modes, while achieving a wide tuning range. To verify the concept, a mm-wave VCO that operates at 30-GHz is designed in a commercial 0.18-um CMOS technology, with an approximate simulated tuning range of 20%. A dual-mode oscillator is also designed in a 0.13-um technology at 60-GHz.

This book was released on 2015 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demands for high data-rate communications and high-precision sensing applications have pushed wireless systems towards higher operating frequencies where wider bandwidth is available. Examples of such applications include 60 GHz indoor communications and vehicular RADAR around 77 GHz. High-speed frequency synthesizers integrated in a CMOS process, with wide operating bandwidth, and low phase noise are key to low-cost transceiver implementations for such applications. The requirement to operate over a wide span of carrier frequencies arises from two key sources. The system itself often requires a wide tuning range, in excess of 5-10% of the carrier frequency. Further, it is necessary to compensate for the uncertainty in operating frequencies, caused by process and temperature variations. This dissertation introduces a dual-mode voltage-controlled oscillator (VCO) topology, embedded in a frequency synthesizer, for wideband operation. The VCO can operate in two oscillation modes by reconfiguring the active negative resistance core around the LC tank that is employed as the resonator element in the oscillator. A key aspect to the design is that the switches used for mode reconfiguration do not contribute to the tank loss. The frequency spacing of the two modes is determined by an accurate inductor ratio. It is demonstrated through analysis that in order to ensure mode-switching, the size of the switches needs be larger than a critical value, which is a function of the electrical properties of the cross-coupled, negative resistance core, as well as the resonator used in the design. The impact of noise injection and mismatch on switching behavior is also analyzed. The VCO topology has been implemented in a 65nm CMOS process. The design demonstrates measured tuning ranges of 56.9 GHz to 65.4 GHz, and 64.6 GHz to 75.3 GHz, in the two respective modes, for a total effective tuning range of 28%. The oscillator consumes 13 mW, with a 1 V-supply, and its Figure of Merit with tuning range (FOM[subscript T]) is -177.2 dB. An integer-N frequency synthesizer that employs the dual-mode VCO, has also been designed and verified in a 65 nm CMOS process. The synthesizer has a locking range from 56 GHz to 63.9 GHz in its low frequency mode. The total power consumption of the synthesizer, including output buffers, is approximately 50 mW. The in-band phase noise, at a locked frequency of 63.04 GHz, is -88.4 dBc/Hz at 1 MHz offset.

This book was released on 2012-12-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of High-Performance CMOS Voltage-Controlled Oscillators presents a phase noise modeling framework for CMOS ring oscillators. The analysis considers both linear and nonlinear operation. It indicates that fast rail-to-rail switching has to be achieved to minimize phase noise. Additionally, in conventional design the flicker noise in the bias circuit can potentially dominate the phase noise at low offset frequencies. Therefore, for narrow bandwidth PLLs, noise up conversion for the bias circuits should be minimized. We define the effective Q factor (Qeff) for ring oscillators and predict its increase for CMOS processes with smaller feature sizes. Our phase noise analysis is validated via simulation and measurement results. The digital switching noise coupled through the power supply and substrate is usually the dominant source of clock jitter. Improving the supply and substrate noise immunity of a PLL is a challenging job in hostile environments such as a microprocessor chip where millions of digital gates are present.

Kraemer and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide regulations for short range communication devices allow the unlicensed use of several Gigahertz of bandwidth in the frequency band around 60GHz. This 60GHz band is ideally suited for applications like very high data rate, energy-autonomous wireless sensor networks or Gbit/s multimedia links with low power constraints. Not long ago, radio interfaces that operate in the millimeter-wave frequency range could only be realized using expensive compound semiconductor technologies. Today, the latest sub-micron CMOS technologies can be used to design 60GHz radio frequency integrated circuits (RFICs)at very low cost in mass production. This thesis is part of an effort to realize a low power System in Package (SiP) including both the radio interface (with baseband and RF circuitry) and an antenna array to directly transmit and receive a 60GHz signal. The first part of this thesis deals with the design of the low power RF transceiver front-end for the radio interface. The key building blocks of this RF front-end (amplifiers, mixers and a voltage controlled oscillator (VCO)) are designed, realized and measured using the 65nm CMOS technology of ST Microelectronics. Full custom active and passive devices are developed for the use within these building blocks. An important step towards the full integration of the RF transceiver front-end is the assembly of these building blocks to form basic transmitter and receiver chips. Circuits with small chip size and low power consumption compared to the state of the art have been accomplished.The second part of this thesis concerns the development of behavioral models for the designed building blocks. These system level models are necessary to simulate the behavior of the entire SiP, which becomes too complex when using detailed circuit level models. In particular, a novel technique to model the transient, steady state and phase noise behavior of the VCO in the hardware description language VHDL-AMS is proposed and implemented. The model uses a state space description to describe the dynamic behavior of the VCO. Its nonlinearity is approximated by artificial neural networks. A drastic reduction of simulation time with respect to the circuit level model has been achieved, while at the same time maintaining a very high level of accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the design of CMOS millimeter-wave voltage controlled oscillators. Varactor, transistor, and inductor designs are optimized to reduce the parasitic capacitances. An investigation of tradeoff between quality factor and tuning range for MOS varactors at 24 GHz has shown that the polysilicon gate lengths between 0.18 and 0.24 micrometer result in both good quality factor (>12) and Cmax/Cmin ratio (~3) in the 0.13-micrometer CMOS process used for the study. The components were utilized to realize a VCO operating around 60 GHz with a tuning range of 5.8 GHz. A 99-GHz VCO with a tuning range of 2.5 GHz, phase noise of --102.7 dBc/Hz at 10-MHz offset and power consumption of 7-15 mW from a 1.5-V supply and a 105-GHz VCO are also demonstrated. This is the CMOS circuit with the highest fundamental operating frequency. The lumped element approach can be used even for VCOs operating near 100-GHz and it results in a smaller circuit area.
