Comparative analysis of different Current mirror using 0.35µm and its Application

Current mode circuits have come to knowledge as compared to voltage mode circuits in recent days because of their properties like low voltage requirement, high slew rate and wider bandwidth The circuit made by current mode technique uses small area, consumes less power dissipation and achieves high operation speed. Current mirrors are the main structures of almost all analog circuits. Current mirror provides high performance, low voltage and low power consumption to its circuits. In the first section of this paper we will analyze and compare the performance parameters of different current mirrors in 350 nm technology in Xilinx xmanager (mentor graphics) tool and in the other section we will show its application in analog circuits. The performance parameters are output impedance, power dissipation, threshold voltage and Trans conductance.
