Abstract
A circuit for compensating for an offset voltage in a PhotoDetector Integrated Circuit (PDIC). The circuit includes a temperature detection unit, a current transfer unit and a current adjustment unit. The temperature detection unit generates a current that varies with variation in surrounding temperature. The current transfer unit transfers the generated current. The current adjustment unit adjusts the current transferred from the current transfer unit at a predetermined ratio and outputs the adjusted current.
