A 200-MHz fully-differential CMOS front-end with an on-chip inductor for magnetic resonance imaging
Abstract
Recently, there is a growing interest in applying electronic circuit design for
biomedical applications, especially in the area of nuclear magnetic resonance (NMR).
NMR has been used for many years as a spectroscopy technique for analytical chem-
istry. Previous studies have demonstrated the design and fabrication of planar spiral
inductors (microcoils) that serve as detectors for nuclear magnetic resonance mi-
crospectroscopy.
The goal of this research was to analyze, design, and test a prototype integrated
sensor, which consisted of a similar microcoil detector with analog components to
form a multiple-channel front-end for a magnetic resonance imaging (MRI) system to
perform microspectroscopy. The research has succeeded in producing good function-
ality for a multiple-channel sensor. The sensor met expectations compared to similar
one-channel systems through experiments in channel separation and good signal-to-
noise ratios.
