摘要：Current mirror (CM) circuit has served as the basic building block in analog circuit design since theintroduction of integrated circuit. In this paper, various low-voltage, high impedance gate-driven current mirror circuitshave been discussed. The circuits are implemented in GDPK 180nm CMOS process and the simulation is done usingCadence Spectre. Various parameters of the circuits such as current linearity, output impedance, dc transmission error,power consumption, leakage power etc. have been analyzed and discussed. Analysis of these circuits shows thatdifferent circuits can be used in different applications depending upon their characteristics. The total powerconsumption is reduced by 110% in the improved gate-driven current mirror (CM) design and hence can be used forpower efficient applications where as the cascode configuration is best suited for high current swing applications due toits high current linearity range
