Coupled timing oscillators

摘要

Coupled timing oscillators are described. The coupling may be electrical, mechanical, or electromechanical in some instances. In some cases, the timing oscillators include mechanical resonators. Any number of timing oscillators may be coupled. The coupled timing oscillators may be operated cooperatively to produce an oscillating signal with improved signal characteristics, such as phase noise and jitter.
