Title (EN) A LOW NOISE BANDGAP REFERENCE APPARATUS
(FR) APPAREIL DE RÉFÉRENCE À BANDE INTERDITE À FAIBLE BRUIT
Abstract:
(EN) An apparatus comprising: a first supply node; a second supply node; a first transistor coupled to the first supply node, the first transistor is to provide a first current which is complementary to absolute temperature (CTAT); a second transistor coupled to the first supply node, the second transistor is to provide a second current which is proportional to absolute temperature (PTAT); a resistive device coupled in series at a node with the first and second transistors, and coupled to the second supply node, wherein the node is to sum the CTAT and the PTAT currents.
(FR) L'invention concerne un appareil comprenant : un premier nœud d'alimentation ; un second nœud d'alimentation ; un premier transistor couplé au premier nœud d'alimentation, le premier transistor étant destiné à fournir un premier courant qui est complémentaire à la température absolue (CTAT) ; un second transistor couplé au premier nœud d'alimentation, le second transistor étant destiné à fournir un second courant qui est proportionnel à la température absolue (PTAT) ; un dispositif résistif couplé en série au niveau d'un nœud avec le premier et le second transistor, et couplé au second nœud d'alimentation, le nœud étant destiné à additionner les courants CTAT et PTAT.
