A systematic study of current conveyor and its applications in filters

Angebote / Angebote:

Current conveyor is considered a well-known active element. Currently, a lot of new applications using current conveyors were proposed and new applications will be designed because current conveyor can be used in various electronic circuits. Current conveyor can be considered universal active element. Current conveyor is a current mode based analog circuit. 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. In the next step we have simulated all the three generations of current conveyor using CMOS 0.35µm technology in Mentor graphics software and verified the results of the circuits using their tables through their simulated waveform. Then we have compared all the three generations and the best one is used to make the circuit of low pass filter using current conveyor. Now this low pass filter using current conveyor is then compared with the low pass filter made by using op-amp.
