Current Conveyors have been used as a basic building block in a variety of electronic circuit in instrumentation and communication systems. Today they replace the conventional OPAMP in so many applications such as active filters, oscillators, analog signal processing and A/D, D/Convertors. Current conveyor is a high performance analog circuit design block based on current mode and voltage mode approach. It is basically a unity gain element that exhibits high linearity, wide dynamic range, high bandwidth and better high frequency performance. The current conveyor is a combination of voltage as well as current follower. Current conveyor has the advantages of a wide current and voltage bandwidths. We use a translinear configuration for first, second and third generation current conveyor. Here, Sinusoidal oscillator by using CCI CCII and CCIII perform good accuracy and frequency response at 1.5V supply voltage. The current conveyor is simulated in terms of voltage offset, current offset, current bandwidth and voltage bandwidth in 180nm CMOS technology using Mentor Graphics tools.
