Description:

Claim:

This invention relates to circuits including semiconductor junction devices and more particularly to means for compensating for activity changes in semiconductor devices that are used for switching purposes. While the invention may be used in connection with many devices incorporating semiconductor materials with P-N junctions, such as transistors, diodes, and the like, it finds especially advantageous use in connection with semiconductor junction photocells in which the back resistance varies inversely with received light.
