Performance Enhancement of Current Follower Transconductance Amplifier (CFTA) and its Application as Filter

Abstract

This paper presents a modified Current Follower Transconductance Amplifier (CFTA). It provides the essential features of high transconductance, wide bandwidth besides a wide linear range. It records the highest transconductance of 18.2[Formula: see text]mS and power dissipation of 1.12[Formula: see text]mW. Moreover, the linear range ([Formula: see text] versus [Formula: see text]) of CFTA is found as [Formula: see text][Formula: see text][Formula: see text]A. All these essential performance parameters are found much better than the available literature. As an application, a novel second-order universal filter is implemented using the proposed CFTA. It is found that the performance of the filter improves with the use of the proposed CFTA.
