摘要:

采用Burr-Brown 公司的10MHz、12Bit A/D采样器件设计了一块基于PC总线的高速A/D采集卡,给出了核磁共振实验结果,并讨论了高速ADC在谱仪简化设计中的应用.

关键词: FPGA, 高速数据采集, 简化设计

Abstract:

The present article employs a piece of ADS804 (Burr-Brown, USA) Integrated C ircuit to design a high-speed Analog-to-Digital Conversion card, which is bas ed on  the ISA bus of the popular personal computer. Nuclear magnetic resonance spectra  obtained with the ADC are given. The application of high-speed ADC to the sim plified design of the NMR spectrometer is also discussed.

Key words: High-speed sampling, FPGA, Simplified design
