Abstract

Eine Schaltungsanordnung zum Ansteuern eines optoelektronischen Bauelements umfasst einen ersten Knoten, einen zweiten Knoten, einen dritten Knotenund einen vierten Knoten. Zwischen dem ersten Knotenund dem vierten Knotenist eine Versorgungsspannung anlegbar. Der erste Knotenist mit dem zweiten Knotenverbunden. Zwischen dem zweiten Knotenund dem dritten Knotenkann ein optoelektronisches Bauelement angeordnet werden. Zwischen dem dritten Knotenund dem vierten Knotenistein erster Transistor zum Schalten eines Kanals zwischen dem dritten Knotenund dem vierten Knotenangeordnet. Zwischen dem ersten Knotenund dem dritten Knotenist eine Reihenschaltung mit einem ersten Widerstandund einer Spule angeordnet.
