    摘要: 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.

    摘要: 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.
