N2 - This paper presents the design of low noise CMOS pre-amplifiers based on photoelectric detection systems, which can directly affect the detecting precision of the whole systems. The design of pre-amplifier circuit from 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 a large dynamic range was designed. This paper analyzes the sources of photoelectric detection circuit internal noise, and gives the formulas of internal noise, designs a variable equivalent load photoelectric conversion circuit, and is verified by experiments. Then the result is used to reduce the noise of CMOS based operational amplifiers and finally implement the design work of pre-amp using 0.5μm CMOS Technology.
