Current mirror

摘要

Some embodiments of the system comprise a current mirror with two switches (a first switch and a second switch) and two compensation circuits (a first compensation circuit and a second compensation circuit). In one embodiment, the first compensation circuit adjusts a drain voltage of the second switch based on a drain voltage of the first switch, and the second compensation circuit adjusts a current through the first switch based on the drain voltage of the second switch.
