  • Appl. No.:
    10/743219
  • Inventors:
    Alan L. Westwick - Austin TX, US
    Timothy J. Dupuis - Austin TX, US
    Susanne A. Paul - Austin TX, US
  • Assignee:
    Silicon Laboratories Inc. - Austin TX
  • International Classification:
    H03F 3/04
  • US Classification:
    330301, 330135, 330165, 330188
  • Abstract:
    A method and apparatus provides an input structure for a power amplifier. In one example, the input structure has an input network and a predriver circuit to provide an input signal to the power amplifier. The input network includes a transformer for helping to maintain a constant input impedance. The predriver includes a limiting amplifier that provides isolation between the power amplifier and the RF input. A DC feedback circuit is used by the predriver that maintains the DC level of the inverters to a desired level.

  • Filed:
    Mar 31, 2005
  • Appl. No.:
    11/095229
  • Inventors:
    Alan L. Westwick - Austin TX, US
    Douglas R. Holberg - Wimberley TX, US
  • Assignee:
    Silicon Laboratories Inc. - Austin TX
  • International Classification:
    H04B 1/40
  • US Classification:
    455 85, 455574, 455 86, 455141, 343 16
  • Abstract:
    An apparatus and method for calibrating a non-crystal oscillator in a transceiver unit using a crystal-oscillator includes the step of establishing a time base based upon oscillations of the crystal oscillator. A comparison of the number of oscillations for the non-crystal oscillator and the crystal oscillator is made during a known time period is made. An adjustment is determined based upon the established time base and the compared number of oscillations. The transceiving of the transceiver unit is then controlled based upon this adjustment.
