Current-Mode First-Order Highpass, Lowpass, and Allpass Filters Using Two ICCIIs

In this paper, a new current-mode first-order filter circuit using two inverting second-generation current conveyors (ICCIIs) is presented. The proposed circuit employs two ICCIIs, one capacitor and one resistor. It can realize all first-order filter functions, which are, highpass, lowpass, and allpass responses. Filter performances are simulated by HSPICE to verify the theoretical predictions.
