Abstract
(EN)
An oscillator circuit is provided with an oscillator, a filter for filtering the monitor signal outputted from the oscillator to output the filtered signal, a drive part for amplifying the filtered signal outputted from the filter to generate a drive signal, and a control unit which operates in a manner so as to adjust the pass characteristic of the filter on the basis of the monitor signal. The oscillator is driven by the drive signal and oscillates, and outputs the monitor signal according to the oscillation. The oscillator circuit is able to stably oscillate an oscillator.

L'invention concerne un circuit oscillant pourvu d'un oscillateur, d'un filtre pour filtrer le signal de moniteur produit par l'oscillateur pour produire un signal filtré, une partie d'attaque pour amplifier le signal filtré produit par le filtre pour produire un signal d'attaque, et d'une unité de commande dont la fonction est d'ajuster la caractéristique de passage du filtre sur la base du signal de moniteur. L'oscillateur est commandé par le signal d'attaque et oscille, et produit le signal de moniteur en fonction de l'oscillation. Le circuit oscillant est capable de faire osciller un oscillateur de manière stable.
