Abstract

A circuit arrangement generates a resistance behavior with an adjustable positive temperature coefficient. A second ohmic resistance element is connected in parallel with a series circuit of a first ohmic resistance element and a diode element wherein the value of the second ohmic resistance element is set corresponding to the desired temperature coefficient.
