Abstract
A current-mode biquad filter using as active elements unity gain current conveyors is presented. The proposed circuit has one input and three outputs and can simultaneously realize low-pass, band-pass and high-pass responses. The structure, which has all the passive elements grounded and only two capacitors, presents low sensitivities and independent control of ω0 and ω0/Q0. PSPICE simulation results are included. © 2001 IEEE.
