Publication number: 20230318448Abstract: Techniques and mechanisms for determining a mode of operation of a switched capacitor voltage regulator (SCVR). In an embodiment, a controller supports multiple modes of operation of the SCVR, wherein the modes each correspond to a different respective sequence of switch states of a converter core of the SCVR. One of the modes is to provide boost voltage regulation with the SCVR. The controller transitions seamlessly and autonomously between two modes based on respective reference switch states of the two modes. In another embodiment, a mode transition is performed based on a signal which a control sensor generates based on a rate of switch events of the voltage regulator, and predetermined reference information indicating current characteristics of the voltage regulator.Type: ApplicationFiled: April 1, 2022Publication date: October 5, 2023Applicant: Intel CorporationInventors: Tamir Salus, Nicolas Butzen, Arvind Raghavan, Harish Krishnamurthy

Patent number: 8983393Abstract: A process, device and computer-readable storage medium that incorporate teachings of the subject disclosure may include, for example, identifying a wireless device that is unable to distinguish between a non-reduced power subframe and a reduced-power, subframe of a communications protocol including a frame having a pre-defined arrangement of non-reduced power subframes and reduced-power subframes. First and second instructions are sent to the wireless device to respectively perform a first channel quality assessment of a non-reduced power subframe and a second channel quality assessment of a reduced-power subframe. The first and second instructions respectively identify the non-reduced power subframes and the reduced-power subframes within which the first and second channel quality assessments are to be performed. After receiving the first and second channel quality assessments, it is determined whether the channel quality assessment performed by the wireless device includes instantaneous measurements.Type: GrantFiled: December 13, 2012Date of Patent: March 17, 2015Assignee: AT&T Intellectual Property I, LPInventors: Arvind Raghavan, Arunabha Ghosh

Patent number: 8605566Abstract: A circuit can process a sample of a signal to emulate, simulate, or model an effect on the signal. Thus, an emulation circuit can produce a representation of a real-world signal transformation by processing the signal according to one or more signal processing parameters that are characteristic of the real-world signal transformation. The emulation circuit can apply analog signal processing and/or mixed signal processing to the signal. The signal processing can comprise feeding the signal through two signal paths, each having a different delay, and creating a weighted sum of the outputs of the two signal paths. The signal processing can also (or alternatively) comprise routing the signal through a network of delay elements, wherein a bank of switching or routing elements determines the route and thus the resulting delay.Type: GrantFiled: August 25, 2010Date of Patent: December 10, 2013Assignee: Quellan, Inc.Inventors: Bruce C.
