Tuning and Control of an On-Chip Piezoelectric Resonator.

Abstract
From clock signals for digital circuits to frequency references and voltage controlled oscillators for communication systems, oscillators are a fundamental element in many electronic circuits. With the current trend toward smaller and more tightly integrated systems, many applications would benefit greatly from the ability to integrate an oscillator onto a chip.In this thesis, we describe the design and development of a new oscillator technology which makes use of a piezoelectric resonator for frequency control. By using a specially constructed piezoelectric structure, the proposed design exhibits several significant advantages over other currently available technologies including the ability to be manufactured on a silicon substrate. This document presents the design of the tuning and control circuitry for such a resonator as well as experimental results with a macro-scale prototype. Details of a truly single-chip oscillator solution, including the design of on-chip capacitors, switches and an amplifier, are also presented. Tuning of the prototype resonator structure is accomplished electrically and the design has shown frequency tuning of up to 1.5% of the nominal value with a theoretical limit of 40% given the appropriate resonator design.
