Accurate CMOS-based current conveyors

An integrable circuit technique for implementing both positive and negative second-generation current conveyors (CCII) is described. Since the proposed circuits consist of a differential pair, current sources, and current mirrors, the realization method can result in a fully integrated current conveyor. The realization method is suitable for fabrication in CMOS technology. The performance of the CMOS-based CCIIs is discussed in detail. The basic performances are demonstrated and simulation and experimental results are presented. The DC transfer characteristics for converting resistors are linear over the total dynamic range.>
