Patent number: 11600572Abstract: A routing structure between dies is provided, including a trace layer, disposed on a substrate, wherein a plurality of routing paths is embedded in the trace layer. In addition, a first die and a second die are disposed on the trace layer and connected by the routing paths. A spacing gap between the first die and the second die is along a first direction and interfacing edges of the first die and the second die are extending along a second direction perpendicular to the first direction. Each of the routing paths includes a first straight portion in parallel to connect to the interfacing edges. The first straight portion has a slant angle with respect to the first direction other than 0° and 90°.Type: GrantFiled: March 11, 2021Date of Patent: March 7, 2023Assignees: Global Unichip Corporation, Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Wei-Chieh Liao, Hao-Yu Tung, Yu-Cheng Sun, Ming-Hsuan Wang, Igor Elkanovich

Publication number: 20220147127Abstract: Techniques for allocating power budget to a central processing unit (CPU) of a computing device are described. According to an example of the present subject matter, a CPU is operated at default power level corresponding to a thermal design power (TDP) of the computing device. Thereafter, an unused power of the computing device is determined at run-time. The unused power is a difference between an allocated power budget of the component and current power consumption of the component, wherein the allocated power budget is an amount of power allocated to the component based on the TDP of the computing device. Based on the unused power the CPU is operated at a high-performance power level. The high-performance power level is a power level above the default power and up to a maximum power level of the CPU.Type: ApplicationFiled: July 31, 2019Publication date: May 12, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Po Ying Chih, Chao Wen Cheng, Yen Tang Chang, Wei Chieh Liao, Yu Fan Chen, Chien Chen Su

Crystal oscillation circuit, gain stage of crystal oscillation circuit and method for designing same
Patent number: 9537449Abstract: A crystal oscillation circuit, a gain stage of the crystal oscillation circuit and a method for designing the same are provided. The gain stage includes multiple amplifiers and multiple current-limiting resistors. Input terminals of the amplifiers are coupled together to a first bonding pad, wherein transconductances of the amplifiers are different from each other. The first bonding pad is used for electrically coupling to a first terminal of an oscillation crystal module. First terminals of the current-limiting resistors are respectively coupled to output terminals of the amplifiers in a one-on-one manner, and second terminals of the current-limiting resistors are coupled together to a second bonding pad, wherein the second bonding pad is used for electrically coupling to a second terminal of the oscillation crystal module.Type: GrantFiled: September 17, 2015Date of Patent: January 3, 2017Assignee: Faraday Technology Corp.Inventors: Wei-Chieh Liao, Chi-Sheng Liao -
