Abstract
This paper presents a new electronically tunable current-mode universal biquadratic filter with three inputs and single output employing only a single modified current differencing transcondutance amplifier and two grounded capacitors. The proposed filter provides realization of low-pass, band-pass, high-pass, band-stop, and all-pass current responses; employment of grounded capacitors; no requirement with the component-matching conditions and the inverting-type input signals to realize specific filtering; electronic control of the natural frequency and low active and passive sensitivities. Simulation results using PSPICE are given to confirm the presented theory
