CMOS integrated NMR spectrometer

Nuclear Magnetic Resonance (NMR) spectrometers have been in use for many years and are used to provide imaging or analysis of a sample being tested. In general, an NMR spectrometer is comprised of three main components: a pulse sequencer, an NMR transmitter, and an NMR receiver. These components are often costly and large, limiting use. This invention integrates the three major building blocks in a single chip (4 mm²) and uses commercially available process technology. All components are digitally controllable and can be easily interfaced to commercially available micro-controllers. The chip can be used as a stand alone NMR system or as part of a multichannel system. Furthermore, due to small size and the lack of long interconnects, the invention can have a greatly improved signal to noise ratio, and lower power usage than traditional NMR systems.
