Abstract :
In this paper, we present a simple low-voltage MOS cascode current mirror featuring a step response and an output voltage swing comparable to those of a simple mirror and and output resistance comparable to that of a stacked mirror. The proposed mirror operates with an input voltage of Vdiode+VDSsat and can operate on a minimum supply of Vdiode + 2VDSsat. We validate the proposed mirror with a combination of simulated and measured results from a circuit prototyped from transistor arrays fabricated in a 0.5-μm CMOS process through MOSIS.
