This book discusses the importance of proper biasing of devices for stability. The voltage transfer characteristics curve analysis imparts knowledge to design a device as analog amplifier or digital switch. The roles and responsibilities of biasing components are discussed. The procedures of large signal analysis, small signal analysis, input impedance measurement, output impedance measurement, maximum output voltage swing, low frequency analysis and high frequency analysis are generalised and can be used for single, multi, differential and IC amplifiers. Basics of RC circuits, bandwidth estimation, short-cut methods to identify poles’ locations are discussed as well. Unique procedures are discussed to analyse BJT and MOS amplifiers. Every section includes a problem to understand the concept.

Unit-I covers the biasing of BJT devices, various biasing methods, and stabilisation techniques. Large signal analysis and synthesis of biasing circuits are discussed in detail. Unit-II covers the small signal analysis of various types of single stage, multistage and differential BJT amplifiers, measurement of input and output impedances, maximum output voltage swing by considering constraints. It also covers synthesis of BJT amplifiers. Unit-III discusses Large and Small Signal analysis of MOSFET amplifiers. The frequency response of BJT and MOSFET single stage amplifiers are covered in Unit-IV. Based on the concept understood in the single stage MOS amplifiers, Unit-V develops the concepts of current mirrors, various biasing schemes and design of  IC amplifiers.
