Title (EN) VOLTAGE REFERENCE AND SELF-OSCILLATING AMPLIFIER CIRCUIT
(FR) TENSION DE RÉFÉRENCE ET CIRCUIT AMPLIFICATEUR AUTO-OSCILLANT
Abstract:
(EN) A voltage reference (200a) is disclosed, which comprises a voltage divider (202) arranged to be coupled to a voltage supply (204); and a filter circuit (206) arranged to be coupled to output of the voltage divider, the filter circuit includes at least one transistor (208) and a capacitive element (210). When in use, the transistor is configured to operate in cut-off mode to enable the filter circuit to function as an RC low-pass filter to attenuate supply noise of the voltage supply, and to enable the filter circuit to generate a reference voltage based on the voltage supply, the reference voltage substantially free of the supply noise.
(FR) La présente invention concerne une tension de référence (200a) qui comprend un diviseur de tension (202), agencé pour être couplé à une alimentation en tension (204) ; et un circuit filtrant (206) agencé pour être couplé à la sortie du diviseur de tension, le circuit filtrant comprend au moins un transistor (208) et un élément capacitif (210). Lors de l'utilisation, le transistor est configuré pour fonctionner en mode coupure pour permettre au circuit filtrant de fonctionner comme un filtre passe-bas RC pour atténuer le bruit d'alimentation de l'alimentation en tension, et pour permettre au circuit filtrant de générer une tension de référence sur la base de l'alimentation en tension, la tension de référence étant sensiblement exempte du bruit d'alimentation.
