US12237810B1 Vibration compensated interferometric noise suppressed oscillator (INSO)
Vibration compensation is provided for Interferometric Noise Suppressed Oscillators (INSOs). In an INSO the error signal at the mixer output responds linearly to changes in carrier frequency. A vibration compensation signal is summed with the error signal at the input to the feedback amplifier to provide the control signal to the loop phase shifter to suppress close-in phase noise near the carrier frequency and to reduce the effects of mechanical vibrations on oscillator phase noise. The addition of the vibration compensation signal does degrade carrier suppression, hence increases the flicker noise contributed by the INSO's LNA but does so without degrading overall oscillator phase noise. In a frequency tuned configuration, the vibration compensation signal reduces the effects of mechanical vibrations on oscillator phase noise independent of the tuning voltage applied to the phase shifter.
