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.

<p>This thesis deals with the study and comparison of on-chip LC Oscillators, used in energy recovery clocking, in terms of Power, Area of Inductor and change in load capacitance. Simulations show how the frequency of the two oscillators varies when the load capacitance is changed from 5pF to 105pF for a given network resistance. A conventional driver is used as a reference for comparisons of power consumptions of the two oscillators. It has been shown that the efficiency of the two oscillators can exceed that of a conventional driver provided the distribution network resistance is low and the on-chip inductor has a high enough Q value. Conclusions drawn from the simulations, using network resistances varying from 0Ω to 4Ω, show that the selection of the oscillator would depend on the network resistance and the amount of area available for the inductors.</p>
