—Current conveyors are unity gain analog building block having high linearity, provide higher gainbandwidth product and wide dynamic range. The current conveyor is a combination of voltage as well as current
follower. The current conveyors operate at low voltage supplies and consume less power. Current Conveyor structure is
very simple. The First and Second Generation current conveyors are simulated using 90nm CMOS techn ology. The main
features of these current conveyors are low voltage, less power dissipation, high linearity 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.
