Abstract: Clock distribution in an integrated circuit component can comprise the generation of bulk acoustic waves by acoustic transmitters and propagation of the bulk acoustic waves across the substrate where they are received by piezoelectric elements acting as acoustic receivers. Clock distribution can also comprise the generation of surface acoustic waves by acoustic transmitters located on the same substrate surface as the piezoelectric elements. An acoustic transmitter comprises a layer of piezoelectric material that generates an acoustic wave in response to the piezoelectric layer being activated by a clock source signal applied to the acoustic transmitter. The piezoelectric elements convert the acoustic waves into an electrical signal which can be used as a local clock signal for devices and components in the vicinity of the piezoelectric elements or from which such a local clock signal can be derived.

Abstract: Techniques and mechanisms for regulating a temperature of a resonator structure. In an embodiment, a thermoelectric cooler (TEC) is thermally coupled to a resonator which is proximate thereto. The resonator supports operation with an oscillator circuit, wherein a resonance characteristic of the resonator contributes to oscillations of a master clock signal, or other oscillatory signal, which is provided with the oscillator circuit. The TEC provides Peltier functionality to selectively perform either one of heating or cooling the resonator. In another embodiment, the TEC is configured to conduct heat which is transferred via a path between the TEC and the resonator, wherein the path omits any circuitry which is to perform operations which are synchronized based on the oscillatory signal.
