14.1 Introduction

The transistor, most commonly used in electronic circuits, was invented in 1948. The first integrated circuit (IC) came in the market in the mid 1960s. Through continuous research and development, very large scale integrated (VLSI) circuits have been brought in use, resulting in gradual ...
