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,omegao and the balanced operation. PSpice simulation results for the proposed integrators and filters are shown.
