Abstract
The present invention is an oscillator which implements matched resonators which are driven at a same frequency, one hundred-eighty degrees out-of-phase. The resonators may be implemented in a same plane of a printed circuit board and located adjacent to each other, thus the resonators are affected by a same (ex.—same magnitude of) vibration interference. However, in the oscillator embodiments described herein, the vibration interference component cancels out of (ex.—is eliminated from) the oscillator output signal, leaving only the desired component.
