  • US Patent:
    6809504, Oct 26, 2004
  • Filed:
    Mar 21, 2002
  • Appl. No.:
    10/104199
  • Inventors:
    Benjamim Tang - Hawthorne CA
    Ken Ostrom - Palos Verdes Estates CA
    Tim Ng - Monterey Park CA
    Clifford Duong - Fountain Valley CA
  • Assignee:
    Primarion, Inc. - Tempe AZ
  • International Classification:
    G05F 156
  • US Classification:
    323274, 323284, 363 16
  • Abstract:
    A dual loop regulator is configured for improved regulation of a supply voltage for a dynamic load based on the magnitude of changes in the load voltage. An exemplary dual loop regulator comprises a primary voltage regulator configured within a linear loop and a secondary voltage regulator configured within a wideband, non-linear loop. The primary voltage regulator is configured for providing a well-controlled, regulated output voltage to the dynamic load, and for addressing small changes in the output voltage. The secondary voltage regulator is configured for sensing undervoltage and overvoltage conditions at the dynamic load, and for addressing changes greater than a predetermined threshold voltage. To facilitate loop stability, secondary voltage regulator can be configured within the wideband, non-linear loop to have a small gain for small changes, a larger gain for large changes, and/or a substantially finite storage capability such that any large signal oscillations will not be sustained.

  • Assignee:
    TelASIC Communications, Inc. - El Segundo CA
  • International Classification:
    H04L027/08
  • US Classification:
    375345
  • Abstract:
    A signal processing system and method. The inventive system includes a first circuit for distributing an input signal between two or more channels in a current mode of operation. A second circuit is disposed in each of the channels for processing the input signal and providing an output signal in response thereto. A third circuit is provided to combine the signals output by the processing circuit. A fourth circuit is included for controlling the first and the third circuits. In a specific illustrative embodiment, the system further includes a radio frequency stage for downconverting a received signal and providing the input signal in response thereto. In the specific embodiment, the first circuit includes a mixing circuit. The mixing circuit includes Gilbert cells and circuitry for providing automatic gain control for each of the channels individually. The Gilbert cells and the automatic gain control circuitry are driven by a transconductance amplifier and therefore operate in a current mode.

    H02H003/00
    G05F001/44
  • US Classification:
    361 64, 323272
  • Abstract:
    A method, apparatus, and system for providing operating power and transient suppression power to a microelectronic device are disclosed. The system includes a primary regulator to supply nominal operating power and to respond to relatively slow transient events and a transient suppression regulator to respond to fast transient power events. The system also includes a sense circuit to detect when a transient event occurs and to send a signal to the transient suppression regulator to supply or sink current to the load in response to a sensed transient power event.

  • US Classification:
    323274000
  • Abstract:
    Methods and apparatus for regulating power supply according to various aspects of the present invention operate in conjunction with an electronic system configured to interface with a primary voltage regulator.
