In this paper, we present observations of the amplitude and frequency noise of two self-sustained oscillating modes of a single micromechanical resonator under fractional synchronization. The resonant modes which comprise the self-sustained oscillato

Toward the objective of direct angle measurement using a rate integrating gyroscope (RIG) without a minimum rate threshold and with performance limited only by electrical and mechanical thermal noise, in this paper, we present the implementation of a

This paper addresses the impact of cubic nonlinearity on the operation of a rate-integrating gyroscope (RIG). It is demonstrated that below the bifurcation threshold, cubic nonlinearity results in angle-dependent frequency split between the two reson

In this paper we present our observations of the effect of mutual fractional synchronization of two oscillators created from two distinct resonance modes of a single micromechanical resonator on the noise of the oscillators. The modes have a 3:1 frac

In this paper, we study the occurrence of synchronization between the two degenerate resonance modes of a microdisk resonator gyroscope. Recently, schemes involving the simultaneous actuation of the two vibration modes of the gyroscope have been impl

We present an epitaxially-encapsulated 2×2mm2 quad-mass resonator (QMR) with shaped comb fingers for frequency tuning. While shaped electrodes have been used for frequency tuning of linear resonators, the device studied here has very high quality fa

We demonstrate synchronization between two intrinsically coupled oscillators that are created from two distinct vibration modes of a single micromachined disk resonator. The modes have a 3:1 subharmonic frequency relationship and cubic, non-dissipati
