Abstract

In this paper we present a new current-mode electronically tunable universal filter using only plus-type current controlled conveyors (CCCII+s) and grounded capacitors. The proposed circuit can simultaneously realize lowpass, bandpass, and highpass filter functions-all at high impedance outputs. The realization of a notch response does not require additional active elements. The circuit enjoys an independent current control of parameters omega(o) and omega(o)/Q. No element matching conditions are imposed. Both its active and passive sensitivities are low.
