Patent number: 7783275Abstract: A direct conversion satellite tuner is fully integrated on a common substrate. The integrated tuner receives an RF signal having a plurality of channels and down-converts a selected channel directly to baseband for further processing. The integrated tuner includes on-chip local oscillator generation, tunable baseband filters, and DC Offset cancellation. The integrated tuner can be implemented in a completely differential I/Q configuration for improved electrical performance. The entire direct conversion satellite tuner can be fabricated on a single semiconductor substrate using standard CMOS processing, with minimal off-chip components. The tuner configuration described herein is not limited to processing TV signals, and can be utilized to down-convert other RF signals to an IF frequency or baseband.Type: GrantFiled: October 13, 2006Date of Patent: August 24, 2010Assignee: Broadcom CorporationInventors: Myles Wakayama, Dana Vincent Laub, Frank Carr, Afshin Mellati, David S.

Publication number: 20060277231Abstract: An integrated computer system and a method for developing a source code and for generating executable computer programs to be run on multiple wireless devices are provided. A computer system includes a wireless device selector, a universal and concurrent emulator, a build and porting engine, a resource manager, and a provisioning server. The computer system utilizes a source code, a database including attributes of wireless devices, one or more libraries containing generic libraries and specific libraries relating to the wireless devices, and resources for the wireless devices. After certain wireless devices are selected, the universal and concurrent emulator can automatically emulate the selected devices and automatically and concurrently test the source code on the emulated devices. The build and porting engine can automatically generate executable computer programs for at least some or all of the selected wireless devices.Type: ApplicationFiled: July 29, 2005Publication date: December 7, 2006Applicant: Javaground USA, Inc.Inventors: Alexandre Kral, Xavier Kral

Publication number: 20060277209Abstract: Computer methods and apparatus for efficient and automatic development and porting of computer programs for wireless devices are provided. Executables for wireless devices can be automatically generated based on the selection of the wireless devices, attributes of the wireless devices, information from libraries, resources, and a version of the source code. The number of executables can be minimized by grouping or sorting automatically the selected wireless devices into categories, where the number of categories is less than the number of the selected wireless devices. If a selected device fails to meet a grouping test criterion, then the device can be either excluded from being grouped into a category or grouped into a category that closely matches the attributes of the failed device.Type: ApplicationFiled: July 29, 2005Publication date: December 7, 2006Applicant: Javaground USA, Inc.Inventors: Alexandre Kral, Xavier Kral

Patent number: 6985044Abstract: A varactor folding technique reduces noise in controllable electronic oscillators through the use of a series of varactors having relatively small capacitance. A folding circuit provides control signals to the varactors in a sequential manner to provide a relatively smooth change in the total capacitance of the oscillator. Consequently, effective control of the oscillator is achieved with accompanying reductions in oscillator noise such as flicker noise.Type: GrantFiled: October 15, 2004Date of Patent: January 10, 2006Assignee: Broadcom CorporationInventors: Ramon Alejandro Gomez, Lawrence M.
