Comparative Study of the Sinusoidal Oscillator by using Current Conveyor
Gargi Sharma, Jagandeep Kaur, Neeraj Gupta
Abstract: 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.
Keywords: CMOS Current Conveyor, CCI, CCII, CCIII and Miscellaneous symbolic representation of CCI, CCII, CCIII
