Title (EN) LOW-POWER PULSED BANDGAP REFERENCE
(FR) RÉFÉRENCE DE LARGEUR DE BANDE INTERDITE À IMPULSIONS À BASSE PUISSANCE
Abstract:
(EN) An electronic circuit (20, 24) includes a bandgap circuit (48), a capacitor (52), a switch (56) and a control circuit (60). The bandgap circuit is configured to generate a predefined reference voltage. The capacitor is coupled to an output port of the electronic circuit on which an output voltage is to be provided. The switch is connected between the bandgap circuit and the capacitor. The control circuit is configured to control the bandgap circuit and the switch so as to alternate between: first time intervals, during which the bandgap circuit is enabled and connected to the capacitor, the capacitor is charged using the reference voltage generated by the bandgap circuit, and the reference voltage is provided as the output voltage on the output port; and second time intervals, during which the bandgap circuit is disabled and disconnected from the capacitor, and the output voltage on the output port is supplied from the capacitor.
(FR) Un circuit électronique (20, 24) comprend un circuit de largeur de bande interdite (48), un condensateur (52), un commutateur (56) et un circuit de commande (60). Le circuit de largeur de bande interdite est configuré pour générer une tension de référence prédéfinie. Le condensateur est couplé à un port de sortie du circuit électronique sur lequel une tension de sortie doit être fournie. Le commutateur est connecté entre le circuit de largeur de bande interdite et le condensateur. Le circuit de commande est configuré pour commander le circuit de largeur de bande interdite et le commutateur de manière à alterner entre : des premiers intervalles de temps, pendant lesquels le circuit de largeur de bande interdite est activé et connecté au condensateur, le condensateur est chargé au moyen de la tension de référence générée par le circuit de largeur de bande interdite, et la tension de référence est fournie en tant que tension de sortie sur le port de sortie ; et des seconds intervalles de temps, pendant lesquels le circuit de largeur de bande interdite est désactivé et déconnecté du condensateur, et la tension de sortie sur le port de sortie est fournie à partir du condensateur.
