摘要：

A CMOS current mirror (CM) based on the body-driven technique and active feedback scheme is presented. The proposed CM is immune to the threshold voltage limitation and offers much higher accuracy over wider current operating range,than other body-driven CMs. The complete analysis of the input-output characteristics, system dc current transfer error, frequency, and noise performance is provided. By using a 1.5 V/1 V single power supply and 0.18-mum n-well process, SPECTRE simulation results validate the analytical results and the overall good performance in terms of wider input-output voltage swing, lower input resistance, and larger output resistance compared with the conventional high-swing cascode CM.
