Design and Implementation of Different Generations of Current Conveyor using 100nm CMOS Technology

Current conveyors are unity gain analog building block having high linearity, wide dynamic range and provide higher gain-bandwidth product. The current conveyors operate at low voltage supplies and consume less power. It has high input impedance, low output impedance and unity current gain (Iz/Ix=±1) as well as unity voltage gain (Vx/Vy=1). The working principle of Current Conveyors is very simple. The current conveyors can easily be implemented using voltage follower and current mirrors. The proposed current conveyors are simulated using 100nm CMOS technology on Advanced Design System. The main features of these current conveyors are low voltage, less power, high slew rate and wide bandwidth for voltage transfer (Vy to Vx) and current transfer (Ix to Iz) which make them suitable for high frequency and low power applications.
