Current-mode and transimpedance-mode universal biquadratic filter using multiple outputs CCIIs

Abstract

169-174A current-mode and transimpedance-mode universal biquadratic filter with single input and multi-outputs using three multiple outputs second-generation current conveyors (MOCCIIs), five resistors and two grounded capacitors is presented. The proposed circuit can realize current-mode notch, bandpass and lowpass responses, simultaneously. The current-mode highpass and allpass responses can be obtained by interconnection of relevant output currents. Moreover, the transimpedance-mode highpass, bandpass, lowpass, notch and allpass filters can also be obtained, simultaneously, from the proposed circuit
