Abstract: A hybrid resonator includes an acoustic wave resonator (AWR) having a piezoelectric material; a first electrical contact, electrically conductively connected to the piezoelectric material; and a second electrical contact, electrically conductively connected to the piezoelectric material. The hybrid resonator further includes a first resonant circuit, electrically conductively connected in series or parallel to the acoustic wave resonator via at least one of the first electrical contact and the second electrical contact. The resonant circuit includes a first inductor, and a first capacitor; wherein, if the first resonant circuit is electrically conductively connected to the acoustic wave resonator in series, the first inductor and the first capacitor are electrically conductively connected to one another in parallel, and if the first resonant circuit is electrically conductively connected to the acoustic wave resonator in parallel, the first inductor and the first capacitor are electrically conductively connected to one another in series.

Abstract: Systems, methods, and circuitries are provided for generating timing signals with a resonator-based open-loop oscillator circuitry. In one example, a system that generates a timing signal based on a target signal includes a plurality of oscillator units configured to generate a respective plurality of oscillator signals. Each oscillator unit includes a resonator that operates in an open-loop mode to generate a resonator signal having a resonator frequency. The resonator signal is used by core circuitry to generate a respective oscillator signal having a respective oscillator frequency. The resonator frequencies of the resonators in the plurality of oscillator units are different from one another. The system also includes a selector circuitry configured to select one of the plurality of oscillator units based on the target signal and provide a selected oscillator signal generated by the selected oscillator unit as the timing signal.
