ABSTRACT:
Circuits, methods, and systems are disclosed in which a current is provided to compensate for spurious current while receiving signals through a line. For example, the spurious current can be sensed and the compensating current can be approximately equal to the sensed spurious current. The spurious current could include photocurrent from a bright light, and the compensating current can prevent bright light effects.
