New MOS-C biquad filter using the current feedback operational amplifier

摘要

A new MOS-C bandpass-low-pass filter using the current feedback operational amplifier (CFOA) is presented. The filter employs two CFOAs, eight MOS transistors operating in the nonsaturation region, and two grounded capacitors. The proposed MOS-C filter has the advantage of independent control of Q and /spl omega//sub 0/. PSpice simulation results for the proposed filter are given.
