Abstract
A four-Current feedback operational amplifier (CFOA)-based state variable biquad is described which permits the accommodation of or compensation for the z-pin parasitic impedances of the CFOAsand offers a numberof advantages over previously known CFOA-based biquad configurations. The workability of the circuit has been confirmed by SPICE simulation results based on commercially available AD844 type CFOAs.
