  • APPARATUSES AND METHODS INVOLVING SUPPRESSION OF SPURIOUS MODES IN RESONATOR-BASED CIRCUITS
    Publication number: 20240348228
    Abstract: In certain examples, methods and apparatus are directed to a resonator-based circuit which, in operation, has an electrically-conductive band (“band”) at least partially surrounding a center electrode which includes the piezoelectric material of the circuit's resonator. In particular examples, the band acts to electrically load vibrations near resonance and consequently, spurious mode suppression is realized. In more particular example embodiments, the band maintains TE mode while eliminating lateral spurious tones, and in one application-specific example, the resonator-based circuitry and the electrical-conductive band are to provide of facilitate piezoelectric power conversion.

  • Apparatus and methods involving control of piezoelectric resonance circuits
    Patent number: 12047018
    Abstract: In certain examples, methods and semiconductor structures are directed to operation of a piezoelectric-based device (e.g., a DC-DC converter) and such operation may involve selectively switching inputs of the piezoelectric-based device at a modulation frequency and, in response, decoupling of the modulation frequency from output power delivered by the piezoelectric-based device. In some examples, the inputs of the piezoelectric-based device are selectively switched to cause decoupling the modulation frequency from output power delivered by the piezoelectric-based device and/or cause operation of the piezoelectric-based device without spurious mode operation.
