Abstract

Embodiments of a microelectromechanical oscillator are described Embodiments include a timing signal generating system (1500) an a method, the system including a microelectromechanical resonator (1508), and a microelectromechanical resonator drive controller (1501) coupled to the microelectromechanical resonator (1508) to receive an output signal of the microelectromechanical resonator (1508) The microelectromechanical resonator drive controller (1501) comprises circuitry to process the received output signal and to generate an intermittent drive signal applied to the microelectromechanical resonator (1508), wherein the microelectromechanical resonator (1508) is not driven when the intermittent signal is not applied.
