What is Dual-Frequency Piezoelectric Oscillator about?
This document summarizes a conference paper that describes a single-resonator dual-frequency thin-film piezoelectric oscillator. It discusses how a high-order aluminum nitride microresonator supports two high-Q acoustic modes at 35.5MHz and 105.7MHz when operated in atmospheric pressure. A simple two-transistor oscillator circuit is able to excite both modes using the resonator, achieving phase noises of -94dBc/Hz and -88dBc/Hz at 1kHz offset for the low and high frequencies respectively. This dual-frequenc
