Abstract
A current mirror circuit is provided that has a feedback loop that includes a current mirror that provides base current compensation to the bases of the input and output transistors of the current mirror circuit. By employing a current mirror in the feedback loop to provide base current compensation, the minimum power supply voltage of the current mirror circuit is very low, typically less than or equal to about 1.5 V.
