CA 2098028

A low power white noise source is fabricated on an integrated circuit. The noise source includes a bipolar junction transistor (Q BJT) having an emitter terminal coupled to a common circuit potential, a collector terminal coupled to a source of current (CS), and a base terminal coupled through a resistance (R B) to a bias signal (VbiaS). The resistance has a resistance value selected to enhance a noise signal generated by the transistor in a collector current thereof. The noise source further includes a transresistance amplifier (AMP) having an input coupled to the collector terminal for converting the noise signal to a voltage signal (NOISE OUT) having white noise characteristics.

Source de bruit blanc de faible puissance, façonnée sur un circuit intégré. Comprend un transistor bipolaire à jonctions (QBJT) ayant un émetteur porté à un potentiel de circuit commun, un collecteur relié à une source de courant (CS) et une base portée au niveau d'un signal de polarisation (Vbias) à travers une résistance (RB). La résistance a une valeur choisie pour améliorer un signal de bruit produit par le transistor dans un courant collecteur associé. La source de bruit comprend en outre un amplificateur transrésistance (AMP) ayant une entrée couplée au collecteur pour convertir le signal de bruit en un signal de tension (NOISE OUT) ayant des caractéristiques de bruit blanc.
