摘要：

New CMOS realization of the negative-type second-generation current conveyor (CCII-) suitable for low power applications is presented. A dynamic biasing circuit is used to control the bias currents of the output stage and to provide class AB mode of operation. The proposed CCII- features high voltage tracking accuracy and low input impedance as a consequence of negative feedback. The compensation of the current tracking error between the X and the Z terminals is also introduced.
