About the OPENCORE NMR project
Recently I (K.T) have developed an integrated, FPGA-based NMR spectrometer (Rev. Sci. Instrum. 78, 033103 (2007)). Its key feature is to let a single chip of Field-Programmable Gate-Array (FPGA) do all digital jobs required for an NMR spectrometer with core modules written in hardware description language.
Here, a kit for implementing the spectrometer inside FPGA is open to public. This kit, referred to as OPENCORE NMR, is composed of core modules such as pulse programmers, direct-digital synthesizers, a digital receiver composed of a digital quadrature demodulator and a digital low-pass filter, and a PC interface. There modules are written in VHDL, and the source codes are to be available, together with peripheral circuit modules as well as a console software.
A home-built NMR spectrometer can serve complementary roles to a sophisticated commercial spectrometer, should one comes across such new ideas that require heavy modification to hardware inside the spectrometer. This work can lower the barriar of building a handmade NMR spectrometer in the laboratory, and promote novel and exciting NMR experiments.
