CURRENT BACKWARD TRANSCONDUCTANCE AMPLIFIER AND ITS APPLICATIONS

Abstract

Emergence of various current mode analog building blocks is outcome of the considerable progress in analog signal processing. Ever since the introduction of current conveyors as basic building block in analog signal processing, many other active building blocks have been introduced so far. Current mode devices like current conveyor and current conveyor based active elements, seem to have a better closed loop bandwidth performance and signal dynamic range than conventional voltage amplifiers. CBTA is also the outcome of this advancements in the electronics domain. The prime concern is to provide better quality response, introduce versatility and modularity, and to develop circuits which could be better implemented in integrated circuit form. In this dissertation we presented bipolar implementation of CBTA. We realized various basic applications of CBTA like active filters, amplifier, inductor simulator. CBTA simulator inductors are further used in the realization of higher order filters by using replacement technique in LC ladder filters and general all pole technique.
