  • Method and device for the analog processing of a radio signal for a radio frequency receiver
    Patent number: 8059760
    Abstract: A device processes a received radio signal. Circuitry formulates voltage samples of the radio signal. Analog processing of those samples is performed. Then, digital processing is performed on the output of the analog processing. The circuitry for formulating voltage samples is configured to ensure a processing of the samples prior to the digital processing.

  • Method and device for the reduction of the DC component of a signal transposed into baseband, in particular in a receiver of the direct conversion type
    Patent number: 7787853
    Abstract: A method is for reducing a DC component of an input signal transposed into baseband and being generated by a first frequency transposition stage starting from an initial signal and from a transposition signal. The method includes amplifying the transposed input signal in a first amplifier. The first amplifier receives at a DC offset compensation input, a compensation signal extracted from an output signal of a second amplifier subjected to a compensation of a offset DC voltage of the second amplifier. The method also included alternating between receiving at an input of the second amplifier, a first auxiliary signal from an auto-transposition of a transposition signal in a second frequency transposition stage and a second auxiliary signal from a transposition of the initial signal in the second frequency transposition stage with the transposition signal.

  • SYNCHRONOUS DISTRIBUTED OSCILLATOR
    Publication number: 20090302959
    Abstract: A distributed oscillator includes an odd number of serially connected amplifying elements. An output of a last amplifying element is looped back to an input of a first amplifying element via a first transmission line. The oscillator oscillates at a first frequency f1. The oscillator further includes circuitry for injecting a control signal onto the input of the first amplifying element. The control signal has a second frequency f2 which is a sub-multiple of the first frequency f1.
