A novel CMOS current conveyor realization with an electronicallytunable current mode filter suitable for VLSI

摘要

A novel CMOS realization of the second generation current conveyornis given. A circuit which compensates the voltage offset due to channelnlength modulation effect is then developed. The CCII is then used tonrealize a new electronically tunable low-pass-band-pass filter suitablenfor VLSI. Simulation results taking the second-order effects intonaccount indicate the excellent performance of both the CCII circuit andnthe filter over a wide dynamic range
