Abstract
This article presents a three-input two-output current-mode universal biquadratic filter performing completely standard functions: low-pass, high-pass, band-pass, band-reject and all-pass functions, based-on a dual output current controlled current differencing transconductance amplifier (DO-CCCDTA). The features of the circuit are that the bandwidth and pole frequency can be tuned electronically via the input bias currents and that the circuit description is very simple, consisting of merely a single DO-CCCDTA and two grounded capacitors. Additionally, each function response can be selected by suitably selecting input signals. Without any external resistors and using only grounded elements, the proposed circuit is very suitable to further develop into an integrated circuit. PSPICE simulation results are depicted. The given results agree well with the theoretical anticipation. The maximum power consumption is approximately 1.81 mW at ±1.5 V power supply voltages.
