Patent number: 7514665Abstract: A light-receiving amplifier circuit in which diodes are commonly connected to a differential amplifier circuit including a transistor of a differential input stage that is an inverting input unit, and are connected between photodiodes (PDs) biased in a forward direction with respect to a direction of photocurrent, and current supply switch transistors. Current supply switch transistors are each connected in parallel between a differential input transistor and a corresponding PD. When light enters into a first PD, a corresponding transistor is turned ON, while a non-corresponding transistor is turned OFF. A non-corresponding diode becomes biased in a backward direction, so that a photocurrent generated due to the light having entered into a second PD is prevented from flowing into the differential amplifier circuit.Type: GrantFiled: September 20, 2006Date of Patent: April 7, 2009Assignee: Panasonic CorporationInventors: Satoshi Murao, Hideo Fukuda, Shinichi Miyamoto
