摘要

A universal biquadratic filter in voltage mode (VM) and current mode (CM) configuration using single Operation Floating Current Conveyor (OFCC) is presented in this paper. It realizes all standard filter functions i.e. low pass (LP), high pass (HP), band pass (BP), notch and all pass (AP) without changing circuit topology. The proposed multi input multi output (MIMO) circuit has two inputs and two outputs and filter outputs can be obtained simultaneously without modifying circuit topology. Prototype circuit including OFCC has been realized using commercially available IC AD844 and components. Presented circuit has additional advantage of low sensitivity and low components count. Results of both modes are verified through mathematical equations, PSpice simulations and prototype.
