    Abstract: A frequency generation solution controls an oscillator amplitude using two feedback paths to generate high frequency signals with lower power consumption and lower noise. A first feedback path provides continuous control of the oscillator amplitude responsive to an amplitude detected at the oscillator output. A second feedback path provides discrete control of the amplitude regulating parameter(s) of the oscillator responsive to the detected oscillator amplitude. Because the second feedback path enables the adjustment of the amplitude regulating parameter(s), the second feedback path enables an amplifier in the first feedback path to operate at a reduced gain, and thus also at a reduced power and a reduced noise, without jeopardizing the performance of the oscillator.

    Abstract: L'invention concerne un oscillateur hyperfréquences travaillant en bande X.
    Le circuit de l'oscillateur comprend un transistor à effet de champ (1) monté en grille commune. Le circuit d'accord, relié à la source, comprend une capacité variable (2) de type varicap commandée par une tension Vp, et une self (3) en parallèle. La tension de commande Vp est découplée de la masse par une capacité (5). Selon l'invention, le transistor (1), le varicap (2) et la capacité (5) sont intégrés dans un même boîtier sous forme d'un micromodule : la capacité (5) sert d'embase au transistor (1) et au varicap (2) soudés côte à côte. La longueur (L) de la connexion entre le varicap (2) et la source du transistor (1) étant minimale permet d'élargir la bande de fréquences linéaire en fonction de la tension de commande Vp.
    Application aux matériels hyperfréquences.

    Abstract: An oscillator circuit (100) comprising a VCO (105), the VCO comprising a resonator (115) coupled to a first amplifier (110), with an output signal from the resonator (115) being arranged to be the output signal from the VCO. The oscillator circuit (100) also comprises an amplifier (120) connected to receive the output signal from the VCO, with the output signal of the amplifier (120) being arranged to be the output signal from the oscillator circuit. In the oscillator circuit (100), the second amplifier is arranged to provide the VCO with a feedback signal which is in phase with the phase of the output signal from the VCO, and the second amplifier (120) is arranged to have an amplifier gain as a function of frequency which is such that the amplitude of the output signal from the oscillator circuit (100) is constant over an operational frequency range of the oscillator circuit.
