要約
(EN)
Provided is a temperature-compensated oscillation device that has an oscillation circuit for oscillating an oscillator. In the provided oscillation device, when the oscillation frequency is changed by a second control signal after being adjusted by a first control signal, the amount of change in the oscillation frequency due to the second control signal is set to a fixed amount. The oscillation frequency of the oscillation device is adjusted on the basis of both the first control signal and the second control signal, but an oscillation amplitude control unit is also added, said oscillation amplitude control unit allowing the oscillation amplitude of the oscillator to be changed by the second control signal. The provided oscillation device thus allows a fixed amount of oscillation frequency adjustment over a wide range (the full range) of oscillation frequency adjustment due to the first control signal.

Cette invention se rapporte à un dispositif d'oscillation compensé en température qui présente un circuit d'oscillation destiné à faire osciller un oscillateur. Dans le dispositif d'oscillation fourni, lorsque la fréquence d'oscillation est modifiée par un second signal de commande après avoir été réglée par un premier signal de commande, la quantité de modification de la fréquence d'oscillation due au second signal de commande est réglée à une quantité fixe. La fréquence d'oscillation du dispositif d'oscillation est réglée sur la base du premier signal de commande et du second signal de commande, mais une unité de commande d'amplitude d'oscillation est également ajoutée, ladite unité de commande d'amplitude d'oscillation permettant au second signal de commande de modifier l'amplitude d'oscillation de l'oscillateur. Le dispositif d'oscillation fourni permet ainsi une quantité fixe de réglage de la fréquence d'oscillation sur une large plage (la plage complète) de réglage de la fréquence d'oscillation dû au premier signal de commande.

 振動子を発振させるための発振回路を有する温度補償型発振器に対し、第1制御信号により発振周波数を調整した後、更に第2制御信号により発振周波数を変える場合に、第2制御信号による発振周波数の変化量を一定とすることができる発振器を実現する。第1制御信号および第2制御信号に基づいて当該発振器の発振周波数を調整するが、更に、第2制御信号によって前記振動子の発振振幅を可変とする発振振幅制御部を付加し、第1制御信号による発振周波数の調整域の広い範囲(全域)に亘って一定した発振周波数の調整を可能にする。
