Abstract
The charge-sensitive preamplifier circuit is a commonly used front-end circuit for particle detectors.PCB stands for printed circuit board,which has the advantages of high density,light weight,and convenient installation.Therefore,it is widely used in the fab-rication of charge-sensitive preamplifier circuits.This paper mainly conducts an application survey on the charge-sensitive preamplifier circuit,and based on the circuit schematic diagram,completes the development of the PCB,circuit debugging,and per-formance testing.It is compared with the same type of charge-sensitive preamplifiers a-broad.After debugging,the circuit functions reliably with no observed failures.Finally,the performance testing of the charge-sensitive preamplifier circuit is completed,and pa-rameters such as conversion gain,output stability,noise level,and rise time are measured multiple times.Through the comparative analysis of the measurement results,it is found that it has the characteristics of small size,high integration,large conversion gain,good output stability,and low noise level,demonstrating excellent overall performance.关键词
