Abstract:

In this project three different topologies of second generation current conveyor (CCII) have been explained. 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 response. For low voltage low power applications we have used the DTMOS technique in these CCII topologies. The circuits are operated at a low voltage of ±0.5V. PSPICE simulation results using TSMC 0.18μm CMOS technology have been presented for the proposed circuits. We find that the linearity, frequency response have improved using DTMOS technique and the power consumption of the circuits has reduced which has been shown using the simulated results.
