Textbook of Operational Transconductance Amplifier and Analog Integrated Circuits

This book provides a detailed study of Operational Transconductance Amplifier (OTA) based circuits, their realizations and applications. The book is primarily concerned with the building blocks and their applications in linear and nonlinear circuit design, presented in a simplified and methodical way.

The nine chapters cover important building blocks, ideal and non-ideal component simulators, and different types of filters and oscillators, using OTA as the active device. It includes:

The introduction and application of an OTA for the realization of the basic building blocks.
Nonlinear applications of OTAs in comparator, zero crossing detector and schmitt trigger circuits.
Realization of ideal grounded as well as floating inductors, resistors, FDNRs and FDNCs.
Realization of non-ideal grounded and floating inductors.
Realization of component multipliers used in instrumentation systems and the IC fabrication of large valued resistors and capacitors.
OTA-based realizations of biquadratic functions.
Current mode and voltage mode ladder filters.
Realization and study of electronically tunable sinusoidal oscillators.

The book can be used as a reference book by researchers and a textbook for graduate and postgraduate courses in electronic devices or analogue filters. It could also be used in other courses related to analogue, hybrid signals, circuits and systems.
