Abstract

Abstract The trend in VLSI towards single-chip systems leads to the integration of analog and digital functions on a single chip. Field-programmable devices are likely to follow the same trend. Currently, there are many digital field-programmable devices in existence, and more recently analog arrays have been developed; however, there are no field-programmable mixed-analogdigital devices. This thesis describes the design and implementation of a Field-Programmable Mixed-Analog-Digital Array. The design contains a field-programmable analog array, a fieldprogrammable gate array, and a mixed-signal interface that includes analog-to-digital and digitalto-analog converters. The novel concept of reconfigurable data converters is introduced for use in a fieldprogrammable system. The resource and architectural requirements for the Field-Programmable Mixed-Analog-Digital Array is determined by analyzing a set of mixed-signal circuits. Furthermore, the practical issues involved in the design of mixed-signal integrated circuits are addressed. v Acknowledgments I would like to take this opportunity to thank my thesis supervisors, Professors Paul Chowand Glenn Gulak, for their guidance, advice, support, and encouragement throughout the course of my studies. I am also indebted to Edward Lee for his patience in answering all my questions about hischip, and sharing his analog design experience. As well, I would like to thank all of my friends who have made graduate school enjoyable. Iespecially thank David Karchmer, Ramin Khoini-Poorfard, Lysander Lim, Tony Ngai, Ali Sheikholeslami, Qiang Wang, David Yeh for their friendship, encouragement, and technicaladvice. I would also like to thank Bryn Owen and Jaro Pristupa for their technical support. I wish to express my sincerest gratitude to my parents who have always supported mystudies.
