Title (EN) OSCILLATOR CIRCUIT
(FR) MONTAGE OSCILLATEUR
Abstract: front page image
(EN)An oscillator circuit includes a current generator (4) which supplies current to input terminals of capacitors (C0, C1) in a trimmable capacitor array. The input terminals of the capacitors are held at a relatively constant voltage, and thus all of the current from the current generator passes through the desired capacitors of the capacitor array, thus minimizing the effetct of parasitic capacitance.
(FR)Un montage oscillateur comporte un générateur de courant (4) qui fournit du courant à des bornes d'entrées de condensateurs (C0, C1) dans un groupement de condensateurs ajustables. Les bornes d'entrée des condensateurs sont maintenues à une tension relativement constante, et l'intégralité du courant provenant du générateur de courant passe ainsi dans les condensateurs voulus du groupement de condensateurs, ce qui réduit au minimum l'effet de la capacité parasite.
