Design of CMOS CCCII Based on Translinear Loop

A CMOS second generation current controlled conveyors (CCCII) is designed.This circuit is composed of translinear loop,basic current mirrors and self-biased high-swing cascade current mirrors.The paper introduces the principle of the circuit,and gives the result of Hspice simulation.The circuit has some advantages,such as low supply voltage,wide-band,the high accuracy of voltage and current transfer,low-cost,and good practical properties.
