Abstract
(EN)
 A motion sensor provided with: a sensor element that outputs a sense signal in response to a motion that is applied; and a detector circuit that detects motion on the basis of the sense signal. The detector circuit has a sensor element signal amplifier into which the sense signal is input. The operation of the sensor element signal amplifier is switchable between a normal mode and a low noise mode that consumes more power than the normal mode and that has little noise. The motion sensor can detect, with high accuracy, small and large motions.

La présente invention concerne un capteur de mouvement équipé : d'un élément capteur qui délivre un signal de détection en réponse à un mouvement qui est appliqué ; et d'un circuit détecteur qui détecte un mouvement sur la base du signal de détection. Selon l'invention, le circuit détecteur comporte un amplificateur de signal d'élément capteur auquel le signal de détection est délivré. La mise en œuvre de l'amplificateur de signal d'élément capteur peut être commutée entre un mode normal et un mode à faible bruit qui consomme davantage d'énergie que le mode normal et qui présente un faible bruit. Le capteur de mouvement peut détecter de petits et de grands mouvements avec une grande précision.

 モーションセンサは、加えられたモーションに応じてセンス信号を出力するセンサ素子と、センス信号に基づいてモーションを検出する検出回路とを備える。検出回路は、センス信号が入力されるセンサ素子信号増幅器を有する。センサ素子信号増幅器は、通常モードと、通常モードよりも消費電力が大きくかつノイズが小さい低ノイズモードとで切替え可能に動作する。このモーションセンサは、小さいモーションと大きいモーションとを高精度に検出できる。
