Design and Implementation of New Transimpedance Amplifier for Measuring Optical Signal

In the particle detection system, the signal processing circuit is processed by voltage, so after the flow voltage conversion, the signal conditioning circuit is very important. In order to convert weak current signal into voltage signal as much as possible, it is necessary to design a suitable circuit amplification system. This paper mainly designs a circuit system for signal conditioning, including type transresistance amplifier circuit, two stage amplifier circuit and zeroing circuit, etc. The designed circuit system can meet the requirements of amplification through simulation and experimental application.
