A CMOS current mirror with lower than VDS(sat) input voltage requirement is presented. It is shown that the structure can be modified to provide cascode-type output resistance for output voltages even lower than 2 VDS(sat). The topology of the proposed current mirror allows low distortion operation from a single 1.5V supply, which makes it attractive for low-voltage applications.
