This paper presents a new second order multifunction filter using one active element, requiring only 'twelve' CMOS transistors, and four passive elements. The proposed circuit realizes voltage-mode low-pass, high-pass and band-pass functions with the advantages of minimum component count structure, high Q possibility, and high frequency potential.

This paper presents an electronically tunable current-mode universal biquad filter based on the current controlled current conveyor transconductance amplifiers (CCCCTAs). The proposed filter employs only three CCCCTAs, two capacitors one of which is permanently grounded. The proposed filter realizes low pass (LP), band pass (BP) and high pass (HP) responses(More)
