Electronics Insensitive Tracking for Ultra-Stable Mems Frequency References
We experimentally demonstrate a novel frequency tracking system for ultra-high stability MEMS frequency references. The technique relies on probing the amplitude response at two points to infer the resonance frequency and is implemented using a direct digital synthesizer (DDS) and PID controller system. This approach eliminates sensitivity to the gain and phase of the measurement electronics, which can otherwise lead to undesirable frequency drifts due to aging and temperature variations. This approach is extremely valuable for frequency references that require parts-per-trillion level stability.
