摘　　要：介绍一种小信号测量系统的设计。该系统利用了在系统可编程模拟器件ispPAC10完成模拟前端的多路信号选择、放大、调理(对信号滤波、积分、求和)及缓冲电路的设计。ispPAC10器件加上自调零网络、单片机和ADC构成了完整的小信号测量系统,使得增益可控,并可用LED显示测量值。A kind of small signal measuring system is designed. This system makes use of in-system programmability programmable analog device ispPAC10 to accomplish the designs in the analog front end circuits which include multipath selection, amplification, adjusting(signal smoothing, integration and summing) and buffering circuits. IspPAC10 can be composed a integral small signal measuring system with the self-zero set network, microprocessors and ADC which can control the gain and display the measurement values with LED.
