Abstract: Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) technologies are widely used for physical, chemical, material and biomedical analysis and medical diagnosis. In attempting to design and build NMR/MRI systems that are significantly cheaper and with simpler configuration than the commercially available systems, we designed and built an analog receiver for NMR/MRI spectrometers based on AD607 (complete receiver on a single chip). Compared to the traditional analog receivers, the proposed design uses components with much smaller sizes and has a rather simple structure. In addition, it can work at higher frequency range than conventional digital receivers can. Detailed description of the design and experimental demonstration of the performance of the receiver are given in the paper.
