Patent number: 10461555Abstract: A wired connection, such as USB-C, for charging a sink from a source, has a configuration channel and a power transmission channel. The presence of data on the configuration channel is used to determine that a cable has been disconnected from the power source. This charging system contains a capacitive power converter and a controller for controlling the capacitive power converter. There is also a configuration channel detector, which is arranged to detect the status of the configuration channel and to provide this status to the controller, so that the system can determine that the source has been detached from the bus when no configuration channel data is present.Type: GrantFiled: May 18, 2017Date of Patent: October 29, 2019Assignee: Dialog Semiconductor (UK) LimitedInventors: Sabin Eftimie, Lasse Harju, Manfred Kogler, Amit Bavisi, Sorin Negru

Patent number: 7489914Abstract: The present invention allows for the use of chip-package co-design of RF transceivers and their components by using discrete active devices in conjunction with passive components. Two particular components are described, including voltage controlled oscillators (VCOs) and low noise amplifiers (LNAs). The high quality passive components for use in the VCOs and LNAs may be obtained by the use of embedded passives in organic substrates. Further, the embedded passives may have multi-band characteristics, thereby allowing multi-band VCOs and LNAs to be implemented with fewer components. In situations where size is a concern, the active devices and passive components utilized in an RF transceiver may be implemented in a low form factor module of less than 1.1 mm thick according to an embodiment of the invention.Type: GrantFiled: April 25, 2005Date of Patent: February 10, 2009Assignee: Georgia Tech Research CorporationInventors: Vinu Govind, Sidharth Dalmia, Amit Bavisi, Venkatesh Sundraram, Madhavan Swaminathan, George White
