Patent number: 9425747Abstract: A system and method of improving the efficiency in the power consumption of an audio system. In essence, the technique is to adjust the power delivered from the power supply to the analog section, such as the power amplifier, in response to the volume level indicated by the volume control module and/or in response to the detected characteristic of the input audio signal. Thus, in this manner, the analog section is operated in a manner that is related to the level of the signal it is processing. Additionally, the system and method also relate to a technique of adjusting the dynamic ranges of the digital signal and the analog signal to improve the overall dynamic range of the system without needing to consume additional power.Type: GrantFiled: March 3, 2008Date of Patent: August 23, 2016Assignee: QUALCOMM IncorporatedInventors: Seyfollah Bazarjani, Guoqing Miao, Joseph R. Fitzgerald, Prajakt V. Kulkarni, Justin Joseph Rosen Gagne, Gene H. McAllister, Jeffrey Hinrichs, Jan Paul van der Wagt

The second metal redistribution layer includes a cobalt tungsten phosphorous material. In some implementations, the first metal redistribution layer is a copper layer. In some implementations, the semiconductor device further includes a first underbump metallization (UBM) layer and a second underbump metallization (UBM) layer.Type: ApplicationFiled: August 6, 2013Publication date: February 12, 2015Applicant: QUALCOMM IncorporatedInventors: Christine Sung-An Hau-Riege, You-Wen Yau, Kevin Patrick Caffey, Lizabeth Ann Keser, Gene H.

Patent number: 8094052Abstract: Techniques for dynamically selecting circuit elements to combat mismatches are described. In one design, an apparatus includes first, second, and third circuits. The first circuit receives input data and provides first signals that are asserted based on the input data, e.g., with thermometer decoding. The second circuit receives the first signals and provides second signals used to select circuit elements, e.g., current sources, capacitors, resistors, etc. The third circuit generates a control for the second circuit, and the second circuit maps the first signals to the second signals based on this control. In one design, the second circuit includes a set of multiplexers and a control circuit. The multiplexers provides the first signals, circularly rotated by an amount determined by the control, as the second signals. The control circuit accumulates control data (e.g., the input data, pseudo-random data, or a fixed value) with the current control value to obtain new control value.Type: GrantFiled: June 7, 2007Date of Patent: January 10, 2012Assignee: QUALCOMM, IncorporatedInventors: Hayg-Taniel Dabag, Dongwon Seo, Gene H.

Patent number: 5499280Abstract: The clock signal generator of the present invention divides a higher frequency clock down to a frequency that is an uneven sub-multiple of the higher frequency. The input clock to be divided down clocks an 11-bit counter (105-110) that outputs an overflow signal to a D flip-flop (125). The D flip-flop generates a load signal that resets the counter after 1025 clock periods. The load signal also suppresses, after 1025 clock periods, the toggling of another toggle flip-flop (120) that provides a divide by two clock. By suppressing a clock pulse in the divide by two clock, every 1025 clock pulses of the higher frequency clock, the average clock frequency of the divide by two clock is reduced to an uneven sub-multiple of the higher clock frequency.Type: GrantFiled: February 2, 1995Date of Patent: March 12, 1996Assignee: QUALCOMM IncorporatedInventors: Nathaniel B. Wilson, Gene H. McAllister
