Current-mode universal filter using translinear current conveyors

This paper presents a new current-mode universal filter with three inputs and three outputs employing only two multiple-output current-controlled current conveyors and two grounded capacitors. The proposed circuit can simultaneously realize of lowpass, bandpass, highpass and bandstop current responses from same configuration. The proposed filter also enjoys an independent current control of parameters natural angular frequency and quality factor through adjusting the bias currents of the translinear current conveyors. The proposed configuration no requires of any cancellation constrain for realizing all the filter responses. The characteristics of the proposed circuit are simulated using PSPICE to confirm the theory.
