ABSTRACT:
A constant-current circuit which has four MOS transistors. The first and second MOS transistors are driven at a constant current ratio corresponding to a ratio of gate-width and gate-length ratios of the third and fourth MOS transistors. The third and fourth MOS transistors are configured as a current mirror circuit, and are chosen to have different gate-width and gate-length ratios from one another.
