Current conveyors are unity gain active building block having high linearity, wide dynamic range and provide higher gain-bandwidth product. The current conveyors operate at low voltage supply and consume less power. It has high input impedance, low output impedance, high CMRR and high slew rate. The working principle of Current Conveyors is very simple and similar to the bipolar transistors. That can easily be explained with help of emitter follower and current mirrors. Now-a-days current conveyors are available in integrated circuit forms. Both BJT and MOS technology is used for developing current conveyor ICs. This paper highlights on historical and technical development of current conveyors right from CCI, CCII and CCIII to recent developments and their linear, nonlinear circuit applications.
