【 摘 要 】

In this paper we present a new current-modeelectronically tunable universal filter using only plus-typecurrent controlled conveyors (CCCII+s) and groundedcapacitors. The proposed circuit can simultaneouslyrealize lowpass, bandpass, and highpass filter functions—all at high impedance outputs. The realization of a notchresponse does not require additional active elements. Thecircuit enjoys an independent current control ofparameters o ω and . / Q ωo No element matchingconditions are imposed. Both its active and passivesensitivities are low.
