Operation and Modeling of the MOS Transistor has become a standard in academia and industry. Extensively revised and updated, the third edition of this highly acclaimed text provides a thorough treatment of the MOS transistor--the key element of modern microelectronic chips.

Analog design at ultra-low supply voltages is an important challenge for the semiconductor research community and industry.Analog Circuit Design Techniques at 0.5V covers challenges for the design of MOS analog and RF circuits at a 0.5 V power supply voltage. All design techniques presented are true low voltage techniques - all nodes in the circuits are within the power supply rails. The circuit implementations of body and gate input fully differential amplifiers are also discussed. These building blocks enable us to build continuous-time filters, track-and-hold circuits, and continuous-time sigma delta modulators.Current books on low voltage analog design typically cover techniques for supply voltages down to approximately 1V. This book presents novel ideas and results for operation from much lower supply voltages and the techniques presented are basic circuit techniques that are widely applicable beyond the scope of the presented examples.Analog Circuit Design Techniques at 0.5V is written for analog circuit designers and researchers as well as graduate students studying semiconductors and integrated circuit design.

There is an ever-increasing trend towards putting entire systems on a single chip. This means that analog circuits will have to coexist on the same substrate along with massive digital systems. Since technologies are optimized with these digital systems in mind, designers will have to make do with standard CMOS processes in the years to come. Filters form important blocks in applications ranging from computer disc-drive chips to radio transceivers. This work addresses the theoretical and practical problems encountered in the design of robust, programmable continuous-time filters with very high bandwidths, implemented in low-cost digital CMOS technologies. A high performance programmable filter architecture, called "constant-capacitance scaling", is discussed in detail. This technique has the potential for very high-speed operation, and ensures that frequency response shape, noise and dynamic range are maintained as bandwidth is programmed.

There is an ever increasing trend towards putting entire systems on a single chip. This means that analog circuits will have to coexist on the same substrate along with massive digital systems. Since technologies are optimized with these digital systems in mind, designers will have to make do with standard CMOS processes in the years to come. We address analog filter design from this perspective. Filters form important blocks in applications ranging from computer disc-drive chips to radio transceivers. In this book, we develop the theory and techniques necessary for the implementation of high frequency (hundreds of megahertz) programmable continuous time filters in standard CMOS processes. Since high density poly-poly capacitors are not available in these technologies, alternative capacitor structures have to be found. Met- metal capacitors have low specific capacitance. An alternative is to use the (inherently nonlinear) capacitance formed by MOSFET gates. In Chapter 2, we focus on the use of MOS capacitors as integrating elements. A physics-based model which predicts distortion accurately is presented for a two-terminal MOS structure in accumulation. Distortion in these capacitors as a function of signal swing and bias voltage is computed. Chapter 3 reviews continuous-time filter architectures in the light of bias-dependent integrating capacitors. We also discuss the merits and demerits of various CMOS transconductance elements. The problems encountered in designing high frequency programmable filters are discussed in detail.
