Abstract

A new electronically tunable universal current mode biquad filter structure employing three multiple output current controlled conveyors (MOCCCII) and two grounded capacitors is presented. The proposed filter offers the following advantageous features: low input impedance and high output impedance—a desirable property of current mode filters; realization of low pass, band pass, high pass, notch, and all pass; no matching constraint; low sensitivity performance and use of grounded capacitors suitable for integration. The practical design problems due to nonlinearities of MOCCCIIs have also been addressed. The feasibility of the design is confirmed via SPICE simulations.
