In this paper, a general two-admittance current-mode circuit structure using triple-output OTA is explored to derive new second-order multi-function filters using OTAs with few extra current outputs and with/ without grounded capacitors. Biquads filters have been realized by using various admittances like OTA-simulated resistor, series and parallel OTA-C resonators in the proposed general structure. PSPICE simulation results are also given for the proposed circuits.
