摘要：

A New CMOS resistor based current mirror with extremely low voltage requirement at input (in the range of a few mV) and output voltage requirement of about one V-ds is presented. The proposed structure combines the advantages of wide input swing, wide output swing, large output impedance, low input impedance and high linearity altogether, which make it attractive for high performance low-voltage and low power applications. Pspice simulations show a very low THD of -42.2dB from a single 0.9V supply in 0.18 mu m, input impedance of 239 Omega, output impedance of 1.2M Omega and power dissipation of only 180 mu W. Interestingly, the input and output voltage requirements are only 10mV and 0.1V respectively.
