Title: A 200-MHz fully-differential CMOS front-end with an on-chip inductor for magnetic resonance imaging
Author: Ayala, Julio Enqrique, II
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 .
