Patent number: 9432038Abstract: A semiconductor device fabrication operation is commonly used to manufacture one or more integrated circuits onto a semiconductor substrate. The semiconductor device fabrication operation forms one or more transistors onto an arrangement of fabrication layers to form the one or more integrated circuits which introduces unwanted capacitances, often referred to as parasitic capacitances, into the one or more transistors. The one or more integrated circuits include one or more compensation modules that, when combined with the parasitic capacitances of the one or more transistors, ideally linearizes the non-linearity caused by the parasitic capacitances of the one or more transistors. For example, the one or more compensation modules incorporate a non-linear or a piecewise linear transfer function that is inversely related to the parasitic capacitances of the one or more transistors.Type: GrantFiled: May 7, 2015Date of Patent: August 30, 2016Assignee: Broadcom CorporationInventors: Christopher Ward, Klaas Bult, Iniyavan Elumalai

Patent number: 9432222Abstract: A transmitter's operation is characterized using components having relatively low cost and low complexity. A device includes comparator(s) that compare a transmitter's analog output to predetermined level(s) to generate count(s) associated with analog output range bin(s). Each of the predetermined levels is associated with a corresponding one of the analog output range bins. A transfer function of the transmitter is generated using the comparison count values associated with the analog output range bin(s). A histogram may be generated from the comparison count values associated with the various analog output range bins. An equalizer is implemented to process data that will be transmitted by the transmitter. The equalizer uses equalizer parameter(s) that are selected based on the characterization of the transmitter (e.g., its transfer function, its histogram, etc.). The equalizer may use default or start up parameters until the transmitter's operation is characterized.Type: GrantFiled: December 26, 2013Date of Patent: August 30, 2016Assignee: BROADCOM CORPORATIONInventors: Ramon Alejandro Gomez, Bruce Joseph Currivan, Lin He, Thomas Joseph Kolze, Franciscus Maria Leonardus van der Goes, Jun Wang

Patent number: 9426682Abstract: The present application relates generally to use of radio resources in a radio access network (RAN) and, in more specific, Full-Duplex (FD) transmission on the same carrier. Due to the mobility of the UEs or the non-optimal grouping, two UEs belonging to different groups may be close to each other while performing transmission and cause serious transmission interferences to 5 each other. This is one of the problems which a method in accordance with the invention aims to solve. When the performing the method a RAN triggers a UE to measure 601 first interferences originated from a first group of UEs. Then the RAN triggers the same UE to measure 602 second interferences originated from a second group of the UEs. Finally, the RAN places 603 the UE into the first group, if the first interferences are higher than the second interferences. The both 10 groups of the UEs are composed of such user equipments which share a group-specific transmission pattern.Type: GrantFiled: March 13, 2012Date of Patent: August 23, 2016Assignee: Broadcom CorporationInventors: Pengfei Sun, Xinying Gao, Haiming Wang, Chunyan Gao

Patent number: 9426469Abstract: Systems and methods are provided that allow a deblocking filter and a sample adaptive offset (SAO) filter to be combined in a loop filter stage of a High Efficiency Video Coding (HEVC) decoder. In combining the deblocking filter and the SAO filter, an intermediate buffer may not be utilized, while still allowing for the deblocking filter and the SAO filter to operate substantially in parallel. The order of pixel processing and the parallelization of operation is such that the processing performed by the SAO filter need not hinder the processing performed by the deblocking filter within the loop filter stage. Additionally, and by combining the deblocking filter and the SAO filter without utilizing buffering therebetween, savings in space and cost in implementing the HEVC decoder may be realized.Type: GrantFiled: December 27, 2012Date of Patent: August 23, 2016Assignee: Broadcom CorporationInventor: Timothy Moore Hellman

System and method for using energy efficient ethernet to control energy efficiencies in lower layers
Patent number: 9425984Abstract: A system and method for using energy-efficient Ethernet to control energy efficiency in lower layers. In one example, an energy-efficiency control policy in a first Ethernet device can be configured to determine a need for transitioning of at least a part of the first Ethernet device into an energy saving state. Based on such a determination, an energy-efficiency control signal can be transmitted from the first Ethernet device to a first non-Ethernet device. The receipt of the energy-efficiency control signal by the first non-Ethernet device is used to initiate a transition by the first non-Ethernet device into an energy saving state, which in turn may initiate a transition by downstream non-Ethernet devices into an energy saving state. This process creates a single unified energy-efficiency policy domain.Type: GrantFiled: March 4, 2013Date of Patent: August 23, 2016Assignee: BROADCOM CORPORATIONInventors: Lowell David Lamb, Wael William Diab
