Abstract
A comb enhanced oscillator in which a drive signal from a first oscillator is split into two signals. The first signal is applied to a nonlinear resonator producing a phononic frequency comb of equally spaced resonances. The second signal is passed through an amplitude detector and a phase shifter. In one embodiment, the comb is applied to the phase shifter to correct for AM-PM cross-correlation noise and then applied to a phase lock loop (PLL) for locking to a second oscillator. The output of the second oscillator is used as the output of the comb enhanced oscillator.
