Dynamics-Enabled Frequency Sources (DEFYS)
Abstract
(U) The Dynamics-Enabled Frequency Sources (DEFYS) program will build on recent advances in very small mechanical systems, nonlinear dynamics, and noise management to revolutionize performance of reference oscillators. Since oscillators are a building block of modern electronics any uncertainty in the frequency they produce will cascade into performance limitations of the larger system. This uncertainty often takes the form of phase noise intrinsic to the oscillator or from deleterious external sources and limits performance of a wide range of both military and civilian systems including: radars, communications, sensors, and geo-positioning devices. DEFYS will develop nanoscale mechanical frequency sources that use novel mechanisms in the dynamics to provide a new level of performance in environments of high accelerations or vibrations and temperature variations. Sources developed in this program will provide an unprecedented performance density and will be flexible enough to be integrated into a wide range of applications.
