Patent

CA 2295564

The invention relates to a wake-up circuit for an electronic apparatus, comprising an input circuit (1) for receiving infrared signals and an amplifier (2) connected to said input circuit (1), the output of which amplifier is connected to a switching stage (6) for switching on the apparatus. To improve the signal/noise ratio the invention provides for the input circuit (1) to comprise a parallel circuit with at least two infrared detectors (2 to 5) connected in series and a parallel oscillatory circuit (11), and for the amplifier to be a band-pass amplifier (2), the output of which is connected to a signal detector to which the switching stage (6) is connected.

L'invention concerne un circuit de réveil pour appareil électronique, comportant un circuit d'entrée (1) pour recevoir des signaux infrarouges et un amplificateur (2) connecté au circuit d'entrée (1), dont la sortie est reliée à un étage de commutation (6) pour enclencher l'appareil. Pour améliorer le rapport signal/bruit, il est prévu que le circuit d'entrée (1) contienne un circuit parallèle d'au moins deux couplages en série de détecteurs à infrarouges (2 à 5), ainsi qu'un circuit oscillant parallèle (11), et que l'amplificateur soit un amplificateur passe-bande (2) dont la sortie est reliée à un détecteur de signaux auquel est raccordé l'étage de commutation (6).
