Abstract

A new current-mode multi-function filter is proposed. The filter uses only two operational amplifiers, four operational trans-conductance amplifiers (OTAs) and one multiple-output third-generation current-conveyor (CCIII). Without using any external passive elements, lowpass, highpass, bandpass, notch and allpass responses can be realized without changing the circuit topology and without any matching or cancellation conditions. The parameters omegao and omegao/ Qo, can be electronically tuned by adjusting the bias currents of the OTAs. The proposed circuit enjoys low sensitivities.
