Abstract

Die Erfindung betrifft eine Schaltungsanordnung zum Erzeugen einer Versorgungsspannung in Abhängigkeit von einer der Schaltungsanordnung zugeführten Eingangsspannung. Es ist dazu ein erster Widerstand einerseits mit der Eingangsspannung und andererseits über eine steuerbare Stromquelle mit dem Massepotential verbunden, so daß am Verbindungspunkt des ersten Widerstands mit der steuerbaren Stromquelle (I1) eine reduzierte Spannung anliegt. Einem impedanzwandler wird die reduzierte Spannung an seinem Eingang zugeführt. Er stellt die Versorgungsspannung an seinem Ausgang bereit. Die steuerbare Stromquelle wird in Abhängigkeit der Versorgungsspannung gesteuert. Damit erreicht man eine Verringerung von Störungen auf der Versorgungsspannung bzgl. der Eingangsspannung.
