The Second generation Current Conveyor (CCII) is a powerful and simple analog circuit building block, which can be used for low power and high speed applications. It is flexible and versatile block and a real competitor for the Voltage mode operational amplifier. It can be used to perform all kind of analog signal processing task like amplification, integration, differentiation, multiplication, oscillation, impedance conversion and signal filtering. This book gives overview of various CCII topologies proposed in the last decade.Thee novel CCII topologies have been proposed in this book and are analysed against parametric variations.
