In this paper a novel low input impedance current mirror\/source is proposed. The principle of its operation compared to that of the simple current mirror is discussed. Also are given the comparative simulation results with HSPICE in TSMC 0.18 \u03bcm CMOS which verify the theoretical formulation and operation of the proposed structure. Simulation results show an input resistance for the proposed current mirror about 0.006 \u03a9. This is 4 \u00d7 \u06f1\u06f0\u06f5 times lower than that of the simple one while both working with 1.5 V supply and 50 \u03bcA bias current. It consumes only 161 \u03bcW and exhibits an excellent current error value of Zero at 55 \u03bcA which remains below 0.6% up to 100 \u03bcA. Favorably its minimum output voltage is reduced to 0.2 V<\/span><\/p>\n
