A phase oscillator is an oscillator model where we view the state of the system as going around the simplest loop, a unit circle. In a phase oscillator model, the state variable $\theta$ is called the phase of the oscillator.
Ultra-robust three-axis rotation rate sensor having dual rotors and coupled z detection
PCT designated stageWO2026027158A1Speed measurement using gyroscopic effectsGyroscopes/turn-sensitive devicesCouplingPhase oscillation
The invention relates to a micromechanical rotation rate sensor comprising: a sensor structure having drive structures and detection structures; a sensor substrate; a first partial oscillator having a first detection mass and a second detection mass; a second partial oscillator having a third detection mass and a fourth detection mass; and a coupling structure, characterised in that the coupling structure provides a mechanical coupling between the first partial oscillator and the second partial oscillator, wherein an in-phase oscillation of the first partial oscillator and the second partial oscillator is suppressed by the mechanical coupling.

True random number generators including ring oscillator circuits leveraging frequency and phase collapse events
True random number generators including ring oscillator circuits leveraging frequency and phase collapse events are described. An example ring oscillator circuit (ROC) includes a first oscillating loop comprising a first set of inverters, where the first oscillating loop is to oscillate at a first frequency and phase. The ROC further includes a second oscillating loop comprising a second set of inverters, which differs from the first set of inverters either in terms of a type of inverters or a number of inverters. The second oscillating loop is to oscillate at a second frequency and phase, different from the first frequency and phase. The ROC further includes a third oscillating loop to, as a result of mode switching from a first mode of operation into a second mode of operation, oscillate at a third frequency and phase, different from the first frequency and phase and the second frequency and phase.

Ultra-robust three-axis gyroscope with dual rotors and coupled z-detection
A micromechanical angular rate sensor is described, comprising a sensor structure having drive structures and detection structures, a sensor substrate, and a first partial oscillator having a first detection mass and a second detection mass, and a second partial oscillator having a third detection mass and a fourth detection mass, and a coupling structure, characterized in that the coupling structure provides a mechanical coupling between the first partial oscillator and the second partial oscillator, wherein the mechanical coupling suppresses phase-in-phase oscillation of the first partial oscillator and the second partial oscillator.
