Patent number: 7607112Abstract: A reverse fill pattern is used in an integrated circuit (IC) that comprises a metal layer having slots formed therein in the shape of rhombuses. The distribution of rhombic slots ensures that electrical current is evenly distributed in the conductor, even at the edge regions of the conductor. This even distribution of rhombic slots ensures that electrical current is evenly distributed at least in the central region, and in most if not all cases, across the entire region of the conductor including the edge regions. Thus, the reverse fill pattern prevents current crowding. By preventing current crowding, more stringent metal distribution targets can be met without creating or exacerbating problems associated with IR drop and EM, and without having to add any extra metal to avoid such problems.Type: GrantFiled: December 12, 2006Date of Patent: October 20, 2009Assignee: Agere Systems, Inc.Inventor: Che Choi C. Leung

Patent number: 7464316Abstract: A turbo decoder that calculates alpha, beta and gamma (branch metric) values does not normalize the branch metric but instead applies the normalization factor to the newly calculated extrinsic values before writing them to interleaving memory, resulting in use of less memory than in prior turbo decoders. A compensating factor is applied when the extrinsics are read from interleaving memory. The absence of normalization in the gamma calculation not only conserves memory but also enhances decoder sensitivity.Type: GrantFiled: August 26, 2005Date of Patent: December 9, 2008Assignee: Agere Systems Inc.Inventors: Mark Andrew Bickerstaff, Benjamin John Widdup

Patent number: 7443145Abstract: A switching regulator for generating a regulated output voltage comprises a charging switch, a network with a coil, a capacitor and a diode as well as a control to open and close the charging switch. On the output side, the network has a positive output rail and a negative output rail, wherein the output voltage to be regulated is applied between the positive output rail and the negative output rail. The control is formed to control a change-over switch to connect the control input of the charging switch either to the positive output rail or the negative output rail via a potential coupling means. Thus, for controlling the switch, no individual potential has to be generated, but the potential at the positive output rail or the negative output rail, which is anyway applied, is used for controlling the charging switch. Thereby, the inventive switching regulator can be structured in a simple way and, additionally, provides defined and fast startup without requiring additional startup circuits.Type: GrantFiled: February 27, 2006Date of Patent: October 28, 2008Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Michael Hackner, Roland Ernst, Hans-Peter Hohe

Patent number: 7386446Abstract: If an adaptive prediction algorithm controllable by a speed coefficient is started from to operate with a first adaption speed and a first adaption precision and an accompanying first prediction precision in the case that the speed coefficient has a first value and to operate with a second, compared to the first one, lower adaption speed and a second, but compared to the first one, higher precision in the case that the speed parameter has a second value, the adaption durations occurring after the reset times where the prediction errors are at first increased due to the, not yet, adapted prediction coefficients may be decreased by at first setting the speed parameter to the first value and, after a while, to a second value. After the speed parameter has again been set to the second value after a predetermined duration after the reset times, the prediction errors and thus the residuals to be transmitted are more optimized or smaller than would be possible with the first speed parameter value.Type: GrantFiled: August 3, 2006Date of Patent: June 10, 2008Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Gerald Schuller, Manfred Lutzky, Ulrich Kraemer, Stefan Wabnik, Jens Hirschfeld
