  • SYSTEM AND METHOD FOR STRENGTHENING OF A CIRCUIT ELEMENT TO REDUCE AN INTEGRATED CIRCUIT'S POWER CONSUMPTION
    Publication number: 20140282347
    Abstract: A system and method enable strengthening of flip-Flops (FFs) in an integrated circuit (IC) for the purpose of reducing power consumption. This is achieved by using stability condition (STC) and observability don't-care (ODC) techniques. Strengthening enable is defined as ensuring that a FF later in the fan-out is enabled only when a FF earlier in the fan-out is driving a signal to that later FF. In an embodiment the fan-in of a FF is traversed and the STC or ODC is determined for the FF. Dependent on the determination a STC controller or an ODC controller is added to control the FF's enable signal. In an embodiment the power savings is checked and a controller is added only if there is a reduction in overall power consumption resulting from the addition of the controller.

  • BOOTSTRAPPED SWITCHING CIRCUIT WITH FAST TURN-ON
    Publication number: 20140266392
    Abstract: An apparatus and method for implementing a bootstrapped switching circuit having improved (i.e. faster) turn-on time is provided. In an embodiment, an inner switching loop is implemented in a bootstrapped switching circuit where the inner switching loop is configured to turn on an input switch in the bootstrapped drive circuit independent of the drive circuit output. The embodiment decouples the inner switching loop circuitry from the output drive circuit of the bootstrapped switching circuit, which typically has a larger load capacitance than the inner switching loop. This allows the inner switching loop to turn on the input switch in the bootstrapped switching circuit faster and decreases the turn-on time of the bootstrapped switching circuit.

  • LOW-DISTORTION PROGRAMMABLE CAPACITOR ARRAY
    Publication number: 20140266358
    Abstract: In one example embodiment, a programmable capacitor array is provided for low distortion and minimizing linearity degradation of an input (Vin) by utilizing control circuitry to switch on and off an array of MOSFET switches. The control circuitry turns on a MOSFET to load a capacitance on Vin and turns off the MOSFET to remove the capacitance from Vin in response to a Din control signal. When the intention is to load Vin with the capacitance, the MOSFET is left on continuously. When the intention is to remove or unload the capacitance from Vin, the MOSFET is primarily turned off, however, the MOSFET is still periodically turned on with appropriate voltage levels in response to a clock signal for periods of time when the loading of the capacitance on Vin is tolerable to the system, thereby ensuring minimal linearity degradation of Vin due to the programmable capacitor array system.

  • Managing codec consistency across a communication session
    Patent number: 8837317
    Abstract: A method and system is disclosed for maintaining codec consistency across a communication session. When a communication session is set up for an access terminal (AT) operating in a wireless communication system, a network device, such a base station, can determine a coding rate to assign the AT for its air interface in a manner that accounts for network capacity variations across the session. If the AT is predicted to handoff to multiple sectors during the session, then a coding rate that best accommodates the air interfaces of all the predicted handoff sectors, but that does not result in consistently low coding rates for the AT, may be used.

  • Assignment of air-interface spreading codes in a cellular wireless communication system
    Patent number: 8837415
    Abstract: A method, system, and apparatus for managing spreading codes used in communication over a radio frequency air interface. When a radio access network (RAN) is to assign a spreading code to a mobile station in the coverage area, the RAN may determine which mobile station currently having an assigned traffic channel in the coverage area has a highest forward-link signal quality, and the RAN may select a spreading code based on the spreading code of that determined mobile station's assigned traffic channel. For instance, the RAN may select a spreading code that is quasi-orthogonal to the spreading code of the determined mobile station's assigned traffic channel.

  • Quantization Error Reduction in Constant Output Current Control Drivers
    Publication number: 20140252990
    Abstract: An electronic system and method includes a controller to control a switching power converter in at least two different modes of operation, a normal mode and an error reduction mode. The controller controls an amount of charge pushed (i.e. delivered) by the switching power converter to a load to reduce a charge quantization error. The charge quantization error represents an amount of charge pushed to the load beyond a target charge amount. The controller determines an amount of charge to be pushed to the toad. Based on the amount of charge to be pushed to the load, the controller generates a current control signal that controls a current control switch in the switching power converter. Determination of the control signal depends on whether the controller is operating in normal mode or error reduction mode. The controller attempts to reduce the charge quantization error to avoid power fluctuations.

  • APPARATUS AND METHOD FOR REDUCING SAMPLING CIRCUIT TIMING MISMATCH
    Publication number: 20140253353
    Abstract: An example apparatus, system, and method for sampling in an interleaved sampling circuit having multiple channels. In an embodiment, an input clock is used to synchronize the transitions of sampling clocks from a first to second voltage level, relative to one another. The sampling clocks are input to a sampling circuit. The input clock switches a common switch that pulls each sampling clock to the second voltage level through a common path on input clock transitions from a first to a second clock state. The transition from the first to a second voltage level of each sampling clock triggers a sample taken on one of the channels. The first voltage level may be boosted to drive switches on in the sampling circuit. Synchronizing transitions of the outputs through the common switch and common path reduces timing mismatch between the sampling clocks controlling the channels.

  • DYNAMIC EDITORS FOR FUNCTIONALLY COMPOSED UI
    Publication number: 20140258971
    Abstract: Embodiments include presenting a first user interface (UI) of an executing application, based on model data that defines an appearance of UI elements of the first UI. Concurrent to presenting the first UI, a second UI of a real-time editor is presented. The second UI is configured to receive editing inputs that are to be applied to the model data, to edit the first UI while the application is executing. A first editing input is received at the second UI, which selects particular model data defining particular UI element(s). Based on the first editing input at the second UI, each of the particular UI element(s) is visually distinguished within the first UI. A second editing input is received at the second UI, which provides changes to the model data corresponding to the particular UI element(s). The particular UI element(s) of the first UI are updated to reflect the desired changes.

  • Automated parameter adjustment to compensate self adjusting transmit power and sensitivity level at the node B
    Patent number: 8831671
    Abstract: A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.
