Design of Multi-Output Second Generation Current Controlled Conveyor

Abstract

In the dissertation, an improved translinear based Multi-Output Second Generation Current Controlled Conveyor (MOCCCII) with programmable gain is proposed. The MOCCCII circuit is developed using current mirror with programmable gain and cross coupled current mirrors. The inherent advantages of the proposed circuit are low supply voltage requirements of ±0.85V, small input parasitic resistance of 65.80Ω for a current of 50μA, low power dissipation of 79.39μw, low DC current error of 0.068% for a current 90μA and low DC voltage error of 1.83%. The proposed MOCCCII has been used as a basic building block to develop oscillator, voltage-mode band-pass filter, current-mode band-pass filter, differentiator and integrator. SPICE simulation results using TSMC (Level 53) 0.18μm CMOS Technology have been presented for the proposed CCCII and its applications to validate the performance of the proposed circuits. The performance parameters of the proposed MOCCCII has also been compared with the existing MOCCCII circuits available in literature and the comparison shows that the proposed MOCCCII has low input resistance, low power dissipation and low DC current error.
