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
