摘　　要：介绍了核测量前端仪器小型化的方法,即使用可编程芯片。可编程芯片不仅包括可编程模拟芯片,还包括可编程逻辑芯片。利用可编程芯片实现主放电路可在保证各种技术指标的同时,做到可多个观测点选择显示和进行键盘控制观测结果。The article introduced a method in the design of nucleus measurement, which uses program-mability chip. Programmability chip includes not only analogy chip but also logic chip. In the circuit designing of the main amplifier, on the one hand the value output gets more accurately, on the other hand the instrument gets more intelligent and the miniaturization. After the design, we can control the channel of the output by a small keyboard and observe one of the sixteen output result at a same time.
