Abstract
Official abstract text for this publication.
An amplifier and oscillator system includes a MEMS resonator and a two stage amplifier topology. The MEMS resonator is configured to generate a resonator signal. The two-stage amplifier topology is configured to amplify the resonator signal with a selected trans-impedance gain. Additionally, the two stage amplifier topology yields a feedback resistance that provides the selected trans-impedance gain.
