This paper introduces a current-mode universal biquadratic filter using current controlled current differencing buffered amplifiers (CCCDBAs). The filter circuit is constructed with two CCCDBAs, two current controlled current differencing amplifiers (CCCDAs) and two grounded capacitors. The circuit can realize low-pass, band-pass, high-pass, band-stop and all-pass transfer functions by choosing appropriate...
This article presents a current-mode universal biquadratic filter (low-pass, high-pass, band-pass functions), based on multiple-output current controlled current conveyor transconductance amplifiers (MO-CCCCTAs). The features of the circuit are that: the quality factor and pole frequency can be tuned orthogonally via the input bias currents: the circuit description is very simple, consisting of merely...
