Abstract
A Synchronous Modulation Resonator (SMR) device, the device includes a resonator having coupled to a Vd source and a Vr source, wherein the Vd is DC biased, wherein the Vr is AC, wherein the resonator provides a resonator output in response to Vd and Vr, a Sigma Delta Modulator (SDM) coupled to the resonator and to the Vr source, wherein the SDM provides a signal output in response to the resonator output and to the Vr, and a digital output block coupled to the SDM, wherein the digital output block is configured to provide a digital signal representation of the resonator output, in response to the signal output.
