基于FPGA的微通道板信号处理系统设计与实现

本文提出了一种用于热等离子体探测的微通道板信号处理系统的设计方法。可以通过对前置放大器进行阈值控制，从而解决由于微通道板输出电荷积累而造成的增益下降问题，通过PC端可以实时的观测测量结果。设计中的数据处理模块、通信模块、DA控制模块基于FPGA实现，将所有的数字电路环节集成在一个FPGA芯片中，为系统的小型化、稳定性、抗干扰性和在线修改、升级创造了条件，完成了一体化设计。本文介绍了这种转换的设计思路、硬件框图和软件的实现方法。

Design and Implementation of Signal Processing System for MCP Based on FPGA

This paper presents a signal processing system to detect the signal from micro-channel plate. With the controlling of pre-amplifier's threshold through DA, it can solve the declining of the MCP's signal gain. Besides, It provides measurement results form Serial debugging assistant. The design of data acquisition and processing module, communication module, DA control module is based on FPGA which Provides solutions for the integrated design.At last, the paper introduces both hardware and the software implement for the design.
