In a world where great efforts are spent designing and creating more complex, yet efficient systems, sensing elements and related readout circuits, which constitute an integral part of them, need to be designed fulfilling these constraints, beside the common key parameters, such as high sensitivity, resolution and accuracy. Capacitive sensors and their differential subset provide virtually no energy dissipation, show insensitivity to temperature variations and have the capability to be micromachined directly onto a silicon substrate, together with the readout interface. Designing a readout circuit that takes advantage of these benefits, according to any specific application, is thus of utmost importance. This volume introduces the reader to state-of-the-art techniques and research achievements in interfacing differential capacitance sensors. Technical topics discussed in the book include:▪ Switched capacitor based interfaces;▪ Voltage mode, differential capacitance to time, voltage, digital converters;▪ Current mode interfaces based on standard components;▪ Current mode interfaces based on CCIIs and VCIIs;▪ Principles of second generation current and voltage conveyors. This book gives the reader a comprehensive overview on the working principles, equivalent circuit models and most advanced interfacing techniques for differential capacitive transducers, highlighting benefits and downsides of each option. Electronic interfaces for differential capacitive sensors is an ideal text for academic staff and Masters/research students in electronic and microelectronic engineering.

Analog CMOS Microelectronic Circuits describes novel approaches for analog electronic interfaces design, especially for resistive and capacitive sensors showing a wide variation range, with the intent to cover a lack of solutions in the literature. After an initial description of sensors and main definitions, novel electronic circuits, which do not require any initial calibrations, are described; they show both AC and DC excitation voltage for the employed sensor, and use both voltage-mode and current-mode approaches. The proposed interfaces can be realized both as prototype boards, for fast characterization (in this sense, they can be easily implemented by students and researchers), and as integrated circuits, using modern low-voltage low-power design techniques (in this case, specialist analog microelectronic researchers will find them useful). The primary audience of Analog CMOS Microelectronic Circuits are: analog circuit designers, sensor companies, Ph.D. students on analog microelectronics, undergraduate and postgraduate students in electronic engineering.

"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. " --
