Piezoelectric Non-Linear Nanomechanical Temperature and Acceleration Insensitive Clocks (PENNTAC) Phase 1 Evaluation and Plans for Phase 2

Abstract

During Phase I, the primary objective of the PENNTAC team has been to understand the non-linear dynamics of laterally vibrating aluminum nitride resonators and harness the bifurcation phenomenon in an electronic ascillatro to meet the ? 90 dBc/Hz at 1 kHz offset requirement. By exploiting non-linear dynamics, we were able to even exceed the phase noise metrics at 1 kHz offset (-94 dBc/Hz) for 1 GHz carrier and reduce the noise floor to levels < - 170 dBc/Hz. The use of non-linear dynamics resulted in a net phase noise improvement with respect to the linear case of more than 7 dBc/Hz at 1 kHz offset, and > 20 dBc/Hz at offsets greater than 10 NHz.
