Patent number: 11611346Abstract: 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.Type: GrantFiled: June 21, 2019Date of Patent: March 21, 2023Assignee: Intel CorporationInventors: Catharina Biber, Jason Mix, Mark Carbone, Mohamed A. Abdelmoneum, Joshua Linden Levy, Timo Huusari, Sarah Shahraini

Patent number: 10666304Abstract: An electric circuit includes a compensation circuit. The compensation circuit includes at least one directional coupler with an adjustable coupling factor. The compensation circuit is coupled between a first signal path and a second signal path of the electric circuit via the at least one directional coupler. Furthermore, the electric circuit includes a detector circuit coupled at least to the second signal path. The detector circuit is configured to detect an interfering signal portion of a signal of the first signal path in the second signal path. Furthermore, the electric circuit includes a control circuit. The control circuit is configured to adjust a transfer characteristic of the compensation circuit based on the detected interfering signal portion. Adjusting the transfer characteristic includes adjusting the coupling factor of the at least one directional coupler.Type: GrantFiled: September 29, 2016Date of Patent: May 26, 2020Assignee: Intel CorporationInventors: Timo Huusari, Saku Lahti
