Temperature Compensated IBAR Reference Oscillators

Abstract

This work presents a two-chip automatically temperature-compensated micromechanical IBAR reference oscillator with a temperature drift of 39ppm over 100 ° C. Temperature compensation is provided by a parabolic VPcorrection scheme and provides 10X improvement over previously reported results. Tunable 6MHz, 10MHz, and 20MHz resonators were characterized with… (More)
