Abstract

In this paper, we present anactive compensation method using a voltage buffer to enhance the bandwidth of current feedback operational amplifier (CFOA) based finite gain inverting voltage amplifier for use as stand-alone amplifier. The use of feedback capacitor to this circuit for realizing Butterworth response is also considered. The proposed circuits require one additional CFOA/capacitor. The effect of finite output impedance at z terminal, input resistance at x terminal, and current mirror pole of the CFOA are studied. The circuits considered have been simulated in PSPICE using a behavioral macro-model of the CFOA as well as that of a practical CFOA AD 844.
