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.

Provides a solid foundation for analog, mixed-signal, and RF circuit design theory and practical application The practice of analog, mixed-signal, and radio frequency (RF) circuit design demands a firm grasp of both theoretical principles and their practical implications. Circuit Analysis for Analog, Mixed-Signal and RF Designers offers engineers and students a comprehensive, unified resource grounded in circuit theory that reflects the realities of modern design. Rather than giving only cursory attention to mathematical underpinnings, this book provides extensive coverage of the analytical tools and methods essential to designing reliable and innovative circuits. With clarity and rigor, authors Shanthi Pavan and Gabor C. Temes illuminate the intuition behind a circuit designer’s core tools — combining theory with real-world applications to equip engineers with both the analytical framework and the practical judgment to apply it effectively. Topics covered include: Analysis and synthesis of linear circuitsNoise analysis and calculations in electronic circuitsWeak nonlinearities in electronic circuitsDistributed circuits and the scattering matrixLinear time-varying circuits and systems, developed from first principlesFundamentals of continuous-time filtersSwitched-capacitor circuits, developed from first principlesCircuit Analysis for Analog, Mixed-Signal and RF Designers is ideal for graduate-level courses in analog, mixed-signal, and RF circuit design within electrical and computer engineering programs. It is also a critical reference for practicing circuit designers and engineers looking for deeper theoretical insight into their daily design work.
