### A Current-mode Electronically Controllable Multifunction Biquadratic Filter Using CCCIIs

#### Abstract

This article presents a current-mode multifunction biquadratic filter performing completely standard functions low-pass, high-pass, band-pass, band-reject and all-pass functions. The circuit principle is based on second-generation current-controlled current conveyor (CCCII) with three input terminals and one output terminal. The features of the circuit are that, the pole frequency can be electronically tuned via the input bias currents. The circuit topology is very simple, consisting of merely 2 CCCIIs and 2 grounded capacitors. Without any external resistor and using only grounded elements, the proposed circuit is very comfortable to further develop into an integrated circuit architecture. The PSpice simulation results are shown. The given results agree well with the theoretical anticipation. The total power consumption is approximately 1.87mW at ±1.5V power supply voltages.
