Resonator with reduced acceleration sensitivity and phase noise using time domain switch

A method for providing a resonator with a time domain switch comprising the following steps:

• providing a frame;
• configuring a first oscillator to oscillate with respect to the frame;
• driving the first oscillator at the first oscillator's resonant frequency;
• mounting a first half of a relative position switch to the first oscillator;
• providing a second oscillator having substantially the same resonant frequency as the first oscillator, wherein the first and second oscillators are designed to respond in substantially the same manner to external perturbations to the frame, and wherein when the first oscillator oscillates there is relative motion between the first and second oscillators;
• and
• mounting a second half of the relative position switch to the second oscillator such that as the first and second switch halves pass by each other in each oscillation the relative position switch passes through a closed state;
• and
• determining a period of oscillation as the difference between successive closed states of the relative position switch.
