This book addresses the theoretical and practical circuit and system concepts that underpin the design of reliable and reproducible, high performance, monolithic feedback circuits. It is intended for practicing electronics engineers and students who wish to acquire an insightful understanding of the ways in which open loop topologies, closed loop architectures, and fundamental circuit theoretic issues determine the limits of performance of analog networks. Since many of the problems that underpin high speed digital circuit design are a subet of the analysis and design dilemmas confronted by the wideband analog circuit designers, the book is also germane to high performance digital circuit design.
