“FULLY DIFFERENTIAL ACTIVE BUILDING BLOCKS AND THEIR APPLICATIONSIN SIGNAL PROCESSING

Abstract

In the present dissertation some studies have been carried out on “fully differential active building blocks and their applications in signal processing”. Traditionally in instrumentation systems various signal processing functions such as amplification of the output of transducers, signal generation, filtering of signals are being performed by active circuit elements like operational amplifiers. The most commonly used operational amplifier is the general purpose internally compensated operational amplifier of the 741 type. Though this operational amplifier is a very versatile circuit element but it has some serious limitations like low frequency operation, very small slew rate, ground referred output etc. To overcome these limitations various other active building blocks which have different architecture have been proposed by various researchers from time to time. These include current conveyors, operational transconductance amplifier, various derivatives of current conveyor...
