Abstract:
(EN) An apparatus is described comprising a bandgap reference circuit (102) comprising: an amplifier (104) including first and second inputs and an output; and a bandgap transistor (106) coupled to the output of the amplifier (104) at a control electrode thereof, the bandgap transistor (106) being further coupled commonly to the first and second inputs of the amplifier (104) at a first electrode thereof to form a feedback path. The apparatus further comprises a resistor (114) coupled to the first electrode of the bandgap transistor (106).
(FR) L'invention concerne un appareil équipé d'un circuit de référence à bande interdite (102) qui comprend: un amplificateur (104) présentant des première et seconde entrées et une sortie; et un transistor à bande interdite (106) couplé à la sortie de l'amplificateur (104) au niveau d'une électrode de commande de celui-ci, le transistor à bande interdite (106) étant en outre couplé en commun aux première et seconde entrées de l'amplificateur (104) au niveau d'une première électrode de celui-ci pour former un trajet de rétroaction. L'appareil comprend en outre une résistance (114) couplée à la première électrode du transistor à bande interdite (106).
