Abstract

A new balanced input balanced output switched capacitor (SC) bandpass lowpass filter using the current feedback operational amplifier (CFOA) is presented. The proposed SC biquad filter is based on a new balanced input balanced output lossless and lossy integrators. The introduced filter has the advantage of independent control Q,omega_o and the balanced operation. PSpice simulation results for the proposed integrators and filters are shown.
