ULTRA-HIGH FREQUENCY SELF-SUSTAINING OSCILLATORS, COUPLED OSCILLATORS, VOLTAGE-CONTROLLED OSCILLATORS, AND OSCILLATOR ARRAYS BASED ON VIBRATING NANOELECTROMECHANICAL RESONATORS

摘要

A self-sustaining ultra-high frequency oscillator and method enable the ability to oscillate and output a signal. A balanced bridge circuit is utilized to null an embedding background response. A first vibrating nanoelectromechanical (NEMS) beam resonator is part of one of the branches of the balanced bridge circuit and determines the frequency of the oscillator's output signal. A feedback loop establishes and sets oscillation conditions of the oscillator's signal. Further, the feedback loop connects an output of the first resonator to an input of the balanced bridge circuit.
