SOI for Frequency Synthesis in RF Integrated Circuits

Abstract

The purpose of this research has been to explore the use of the Honeywell silicon on insulator fabrication process for use in a frequency synthesizer. The research includes the fabrication of a frequency synthesizer and ring oscillators which are used to evaluate the fabrication process. Experimental results are compared to the theoretical results, providing some insight into circuit design with the silicon on insulator process. Recommendations are presented to enhance the frequency stability of such circuits. A novel method for reducing phase noise in ring oscillators through manipulation of the floating body is also presented.
