Abstract
The design of the pre-amplifier circuit of photoelectric detector systems can directly affect the detecting precision of the whole systems. The design of pre-amplifier circuit from a photoelectric detector was introduced. The photoelectric conversion circuit，amplifier circuit bandwidth, amplifier circuit noise, amplifier circuit stabilization and other questions were mainly discussed，and an amplifier circuit capable of effectively decreasing the noise, the temperature drift and with a large dynamic range was designed.
