Abstract

A novel CMOS realization of the second generation current conveyor is given. A circuit which compensates the voltage offset due to channel length modulation effect is then developed. The CCII is then used to realize a new electronically tunable low-pass-band-pass filter suitable for VLSI. Simulation results taking the second-order effects into account indicate the excellent performance of both the CCII circuit and the filter over a wide dynamic range
