Operational Amplifiers & Linear ICs

Operational Amplifiers and Linear ICs is designed as a textbook for undergraduate students of electrical engineering, electronics and communication engineering and related courses. Beginning with a discussion of the basic operational amplifier (op-amp) internal circuit, the text explains the operation of voltage followers, no inverting amplifiers and inverting amplifiers. Op-amp parameters and performance limitations are investigated next, followed by the design and analysis of direct-coupled and capacitor-coupled op-amp circuits. The topics discussed include biasing requirements, determination of resistor and capacitor values for a specified gain and frequency response and input and output impedances. The pattern of circuit explanation, design and analysis is followed as the text progresses through a myriad of op-amp and linear IC applications. This third edition features new chapters on noise in op-amp circuits, sinusoidal oscillators, audio power amplifiers, D/A and A/D converters and phase-locked loop. Additional topics treated include IC voltage comparator, IC timer circuits, switching regulators, switched capacitor filters and IC power amplifiers.
