摘要
针对带电粒子探测阵列信号量大、计数率高的要求,设计并实现了基于高速运放芯片、高速ADC芯片的主放大器及模-数转换电路,同时采用51系列单片机控制ADC电路和USB通讯芯片,完成信号的数字化和上传采集。整个系统硬件结构完整,软件控制合理,满足了设计需求。
The charged particle detector array has huge amounts of signal and needs high counting rate. To meet the requirements, a main amplifier and analog-to-digital conversion circuit based on high-speed op-amp chips and ADC chip was designed. A 51-MCU was used to control the circuit of ADC and the USB communication chip. The signals were digitized and uploaded by the MCU-ADC-USB circuit. The whole system has a compact hardware structure and a reasonable controlling software, which meet the design requirements.
