  • Publication number: 20240136243
    Abstract: Described herein are integrated circuit devices that include semiconductor devices near the center of the device, rather than towards the top or bottom of the device. In this arrangement, heat can become trapped inside the device. Metal fill, such as copper, is formed within a portion of the device, e.g., over the semiconductor devices and any front side interconnect structures, to transfer heat away from the semiconductor devices and towards a heat spreader.

  • Patent number: 11411555
    Abstract: Described is a circuit and architecture that combines phase interpolator (PI) mixer with duty cycle correction (DCC), to prevent cross contention between the tristate inverter pairs of the mixer. The control code for the p-type and n-type networks in the PI mixer are decoupled, and DCC mechanism are blended in the PI mixer code decoding scheme to enable a low latency phase interpolation and duty cycle correction. The circuit comprises a first mixer circuitry controllable by a first code; a second mixer circuitry controllable by a second code; a node coupled to outputs of the first and second mixers; and a keeper circuitry coupled to the node, wherein the first and second mixers are tri-stable mixers.

  • Publication number: 20220215147
    Abstract: An integrated circuit system includes a temperature sensor circuit that generates an output indicative of a temperature in an integrated circuit. The integrated circuit system also includes a temperature management controller circuit that compares the temperature indicated by the output of the temperature sensor circuit to a temperature threshold. The integrated circuit system further includes temperature reduction circuitry and/or design compilation techniques and partial or full reconfiguration that controls the temperature in the integrated circuit system. The temperature management controller circuit causes the temperature reduction circuitry to reduce the temperature in response to the temperature indicated by the output of the temperature sensor circuit exceeding the temperature threshold. The temperature sensor circuit, the temperature management controller circuit, and the temperature reduction circuitry may be implemented by soft logic circuits, hard logic circuits, or any combination thereof.
