ABSTRACT:
A first and a second resonator are fabricated monolithically adjacent to one another. The first resonator is the reference resonator. The resonant frequency of the second resonator is offset by a difference frequency Fo from the first resonator. Each resonator is included within an oscillator. A mixer receives the output of both oscillators. A low pass filter receives the mixer output and generates a clock signal whose frequency is equal to the difference frequency Fo.
