Title: Light receiving circuit
Inventor: YAMAMOTO YUJI
IPC: H04B10/60
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a light receiving circuit that has no gain reduction when input light is very small. SOLUTION: A series connection consisting of a 2nd load resistor 3 and a capacitor 4 is connected in parallel with a 1st load resistor 2 connected in series with a light receiving element 1. A differential amplifier circuit consists of transistors(TRs) 7, 8, a constant current source 9 and resistors R3, R4, receives a voltage across the 2nd load resistor as its input and provides an output of a difference between voltages produced across the resistors R3, R4 as its output. When the voltage produced across the 2nd load resistor is zero, the gain of the differential amplifier circuit is not reduced because each of the voltage across the resistors R3, R4 is not zero although the difference between the voltages across the resistors R3, R4 is zero.
