| 英文摘要 | A laser diode driving circuit for driving a laser diode includes a driving transistor which controls a forward current of the laser diode, a photoelectric conversion element which receives an optical output of the laser diode and outputs a photocurrent proportional to the optical output, a converting circuit which converts an external light emission instruction signal into a light emission instruction signal current, and a source grounding circuit which amplifies a current which corresponds to a difference between the light emission instruction signal current from the converting circuit and the photocurrent from the photoelectric conversion element, so as to output an amplified current. This the source grounding circuit applies the amplified current to the driving transistor and controls the driving transistor so that the light emission instruction signal current becomes equal to the photocurrent. |
