摘要 |
A current mirror having an amplification factor K providing a photocurrent compensation current to a node having a mismatch of junction photocurrent. The load device on the input leg of the current mirror has an area 1/K times the device width of the larger device junction area at the node and a device width ratio with drive device of the input leg of a current mirror equal to the ratio of mismatch J at the node.
