Realization of the nullor using two CMOS CCII+s

Abstract

The nullor element is implemented herein by using two positive-type second generation current conveyors (CCII+s). The CCII+s are designed using standard CMOS integrated circuit technology of 0.35μm. The main advantage is the very low parasitic resistance of the CCII+ at terminal X (RX), in order to accomplish the ideal behavior of the nullor. HSPICE simulation results are provided and the usefulness of the designed nullor is highlighted through the implementation of a current-mode universal filter and a sinusoidal oscillator.
