Abstract

A simple CMOS second generation negative current conveyor (CCII-) is presented which is suitable for low supply voltage operation. By restricting the CCII- to applications where the Y input is effectively referenced to signal ground, a greatly simplified circuit topology is realized. With only two devices stacked between the supply rails, low voltage operation is achieved. Internal negative feedback is used to reduce the input resistance of the X input. Simulation results demonstrate the use of the CCII- in lowpass and bandpass filter applications
