Patent number: 9820229Abstract: Methods and apparatuses are described in which dynamic voltage and frequency scaling may be used to save power when processing packets in a wireless communications device. In some cases, inframe detection may allow the device to determine whether to transition from a first (e.g., lower) voltage level to a second (e.g., higher) voltage level to process one or more packets of a received frame. For some packet types the first voltage level may be maintained. In other cases, the device may determine a bandwidth to use from among multiple bandwidths supported by the device. The bandwidth may be determined based on channel conditions. A voltage level may be identified that corresponds to the determined bandwidth and a processing voltage may be scaled to the identified voltage level. The device may be configured to operate in wireless local area network (WLAN) and/or in a cellular network (e.g., LTE).Type: GrantFiled: July 30, 2013Date of Patent: November 14, 2017Assignee: QUALCOMM IncorporatedInventors: Sandip Homchaudhuri, Joseph Duncan, Xiaoru Zhang, MeeLan Lee, Arunkumar Jayaraman, Derrick Chu Lin, Srenik Mehta

Patent number: 9804664Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, using a modulation and coding scheme (MCS) value as a factor for guidance. According to one aspect, the device may be in a reception mode. While in a first power mode, the device may receive control information for incoming data that is being transmitted via a transmission frame. The control information may be located in a first portion of the frame with the data following in a second portion of the frame. The control information may include or otherwise indicate an MCS value corresponding to the MCS applied to the incoming data. Based on the MCS value, the device may be adaptively switched to a second power mode for receiving the incoming data.Type: GrantFiled: May 27, 2014Date of Patent: October 31, 2017Assignee: QUALCOMM IncorporatedInventors: Sandip Homchaudhuri, Paul Husted, MeeLan Lee, Srenik Mehta, Kai Shi, Shahram Abdollahi-Alibeik, Zhanfeng Jia, Soraya Kasnavi, Ning Zhang, David Kuochieh Su, Subramania Sharma Thandaveswaran, Kenneth Gainey, Ian David O'Donnell

Patent number: 8155612Abstract: A wireless device that can process signals according to multiple wireless protocols simultaneously and without signal loss. The wireless device may comprise an antenna and first and second wireless protocol circuitry. The first wireless protocol circuitry comprises a shared gain element that amplifies signals that are processed by each of the first and second wireless protocol circuitry. Since the third signals are amplified by the shared gain element prior to being split out to the respective protocol circuitry, the first and second portions of the amplified third signals do not have significant signal loss relative to the third signals provided by the antenna. Thus the wireless device can receive and process wireless signals according to both the first and second protocols simultaneously without any significant signal losses due to splitting of the receive signal.Type: GrantFiled: November 25, 2008Date of Patent: April 10, 2012Assignee: Qualcomm Atheros, Inc.Inventors: Paul J.

Patent number: 8106715Abstract: In order to decrease the temperature sensitivity of an oscillator output, and obtain a frequency of oscillation that remains stable over variations in temperature, two oscillators may be configured with identical comparators and logic circuitry, but having different oscillation frequencies. The different oscillation frequencies may be achieved by configuring each oscillator with a respective resistor divider circuit configured to adjust the reference voltage at the reference input of the respective comparator. The difference between the respective periods of oscillation of the two oscillators may therefore become independent of the comparator delay, and may only depend on temperature sensitivity of the resistor.Type: GrantFiled: December 4, 2009Date of Patent: January 31, 2012Assignee: Qualcomm Atheros, Inc.Inventors: Bita Nezamfar, Srenik Mehta

Patent number: 7132865Abstract: Parasitic current at the control voltage node of a phase-locked loop (PLL) can significantly reduce performance of the PLL. Off-state transistors in either the charge pump or the filter can cause this parasitic current. A method of canceling a parasitic current generated by the charge pump in the PLL is described. In this method, a leakage current associated with leaky circuits in the charge pump can be determined. An opposing current can be injected to the control voltage node. This opposing current is equal, but opposite, to the leakage current. A method of eliminating a parasitic current generated by the filter in the PLL is also described. In this method, for each programmable capacitor in an unused state, a unity gain buffer can charge the capacitor to the same potential as the control voltage node, thereby providing the same potential on both sides of the switch.Type: GrantFiled: July 23, 2004Date of Patent: November 7, 2006Assignee: Atheros Communications, Inc.Inventors: Manolis Terrovitis, Srenik Mehta
