  • Abstract
    A new paradigm in inertial sensing is presented based on measurement of accurate time intervals using physical proximity switches deposed on a resonating beam structure. This paper discusses the time domain sensing concept and noise sources that can influence the performance of the sensor. The ultimate noise floor (-178 dB/√Hz)is limited by the accuracy of a time-to-digital convertor.
