Abstract

A circuit arrangement is proposed which generates a temperature-dependent output signal that has a virtually ideally quadratic temperature dependency. The circuit arrangement is therefore particularly well suited for high-precision temperature compensation in sensor signal evaluation circuits. At the same time, it is particularly suitable for production by thick-film or thin-film techniques.
