Available in PDF, EPUB and Kindle. Book excerpt: "Many applications require MEMS sensors to operate over wide temperature range, typically from -55 oC to 225 oC. It is desirable to place the sensor readout circuits in close proximity to the sensor devices to improve signal-to-noise ratio and system reliability. Therefore, the sensor readout circuits must also be able to function over the same temperature range as the sensor devices. The main challenges for designing CMOS sensor readout circuits working over wide-temperature range (especially at the high temperature end) include: 1) increased junction leakage current, 2) reduced carrier mobility, and 3) decreased threshold voltage in MOS transistors. In this thesis, constant-gm biasing and other design techniques are used to mitigate the circuit performance degradation at high temperatures and three readout circuits for capacitive MEMS sensors are developed using standard CMOS process which can operate over wide temperature range from -55 oC to 225 oC.First, several proof-of-concept core building blocks are designed and tested, including a constant-gm biasing circuit, a single-ended folded-cascode amplifier, and a fully-differential folded-cascode amplifier with a switched capacitor common mode feedback circuit. The single-ended folded-cascode amplifier showed DC gain of 68.5 dB at 225 °C and DC gain variation of 2.8 dB from -20 °C to 225 °C. The fully-differential folded-cascode amplifier with the switched capacitor common mode feedback circuit showed a DC gain of 68.9 dB and DC gain variation of 2.1 dB from -20 °C to 225 °C. Then, using these core building blocks, three readout circuits for capacitive MEMS sensors were constructed, including: 1) a differential capacitance to voltage readout circuit for sensors with a wide range of the steady-state capacitance values from 0.5 pF to 10 pF, 2) a capacitance to frequency readout circuit which converts the sensor capacitance into digital pulse signal modulated in frequency, and 3) a capacitance to digital readout circuit which uses a sigma-delta technique to convert the input ratio between sensor capacitance and reference capacitance into a high-accuracy digital output. All these three capacitive sensor readout circuits are simulated over temperature range from -55 °C to 225 °C and tested over temperature range from -20 °C to 225 °C. Measurement results show that these circuits have good accuracy and temperature stability over the wide temperature range.All the circuits developed in this thesis are implemented using IBM 0.13 [mu]m standard CMOS technology which incorporates a 2.5 V power for the advantages of high level of integration and low power consumption. The design techniques used here are universal and they can be readily ported to other standard CMOS processes and even SOI processes. Future improvement and development for these circuits are proposed. More sophisticated sensor readout circuits could be built based upon the prototypes developed in this thesis. " --

Available in PDF, EPUB and Kindle. Book excerpt: Sensors find a variety of applications in portable electronics, automotive and biomedical solutions. The demand for low power and high dynamic range makes the design of digital sensor readout circuits quite challenging. Traditionally, these circuits are realized using amplifiers with passive feedback or precision analog comparators which are power hungry and not amenable to technology scaling. This thesis presents design techniques for a low power, amplifier-free, digital sensor current readout circuit. It is realized using an implicit passive integrator, VCO-based quantizer, and mostly digital circuits. A digital IIR filter is used to increase the loop gain and bias the sensor accurately across a wide range of values. Fabricated in a 0.18[micro]m CMOS process, the prototype readout circuit achieves 900pA accuracy over an input current range of 4[micro]A, consumes a total of 77.8[micro]A current, and occupies an active area of 0.36mm2.

Book excerpt: In recent years, there have been growing demands for bandwidth, for both voice and data communications. This has increased the need for high speed systems. The Radio Frequency integrated circuit (RFIC) and wireless market has suddenly expanded to unimaginable dimensions. Devices such as pagers, cellular and cordless phones, cable modems, and RF identification tags are rapidly penetrating all aspects of our lives, evolving from luxury items to indispensable tools. Historically, RFIC's are implemented in III-V compounded semiconductors or in bipolar technologies. The DSP circuits, on the other hand, require small feature sizes to guarantee high speed of operation with low power consumption, hence the use of Complementary Metal-Oxide Semiconductor (CMOS) technologies. CMOS technologies are beginning to satisfy the needs of high-speed analog design, providing the drive for the quest for a complete commercial CMOS transceiver. Driven by the needs for low power, small size and low cost, CMOS RFIC design becomes main stream in modern wireless communication.The challenges are not only to design RF transceivers in CMOS processes, but also to establish design methodologies.

Book excerpt: 1.1 Overview of Lab-on-Chip Laboratory-on-Chip (LoC) is a multidisciplinary approach used for the miniaturization, integration and automation of biological assays or procedures in analytical chemistry [1–3]. Biology and chemistry are experimental sciences that are continuing to evolve and develop new protocols. Each protocol offers step-by-step laboratory instructions, lists of the necessary equipments and required biological and/or chemical substances [4–7]. A biological or chemical laboratory contains various pieces of equipment used for performing such protocols and, as shown in Fig. 1.1, the engineering aspect of LoC design is aiming to embed all these components in a single chip for single-purpose applications. 1.1.1 Main Objectives of LoC Systems Several clear advantages of this technology over conventional approaches, including portability, full automation, ease of operation, low sample consumption and fast assays time, make LoC suitable for many applications including. 1.1.1.1 Highly Throughput Screening To conduct an experiment, a researcher fills a well with the required biological or chemical analytes and keeps the sample in an incubator for some time to allowing the sample to react properly. Afterwards, any changes can be observed using a microscope. In order to quickly conduct millions of biochemical or pharmacolo- cal tests, the researchers will require an automated highly throughput screening (HTS) [8], comprised of a large array of wells, liquid handling devices (e.g., mic- channel, micropump and microvalves [9–11]), a fully controllable incubator and an integrated sensor array, along with the appropriate readout system.

This book was released on 2006-04-18 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-Voltage CMOS Log Companding Analog Design presents in detail state-of-the-art analog circuit techniques for the very low-voltage and low-power design of systems-on-chip in CMOS technologies. The proposed strategy is mainly based on two bases: the Instantaneous Log Companding Theory, and the MOSFET operating in the subthreshold region. The former allows inner compression of the voltage dynamic-range for very low-voltage operation, while the latter is compatible with CMOS technologies and suitable for low-power circuits. The required background on the specific modeling of the MOS transistor for Companding is supplied at the beginning. Following this general approach, a complete set of CMOS basic building blocks is proposed and analyzed for a wide variety of analog signal processing. In particular, the covered areas include: amplification and AGC, arbitrary filtering, PTAT generation, and pulse duration modulation (PDM). For each topic, several case studies are considered to illustrate the design methodology. Also, integrated examples in 1.2um and 0.35um CMOS technologies are reported to verify the good agreement between design equations and experimental data. The resulting analog circuit topologies exhibit very low-voltage (i.e. 1V) and low-power (few tenths of uA) capabilities. Apart from these specific design examples, a real industrial application in the field of hearing aids is also presented as the main demonstrator of all the proposed basic building blocks. This system-on-chip exhibits true 1V operation, high flexibility through digital programmability and very low-power consumption (about 300uA including the Class-D amplifier). As a result, the reported ASIC can meet the specifications of a complete family of common hearing aid models. In conclusion, this book is addressed to both industry ASIC designers who can apply its contents to the synthesis of very low-power systems-on-chip in standard CMOS technologies, as well as to the teachers of modern circuit design in electronic engineering.
