Abstract
In an oscillator circuit (VCOS) having at least one heating element (HE) that keeps the temperature constant, the clock signals (ts) that are formed are conducted via an output connection (AV) to an output (TA) of the oscillator circuit (VCOS). An impedance evaluation unit (WAE) is inserted into this output connection (AV) and detects changes in an impedance or of a resistor (R4, R5) connected to the output (TA) and the heating element (HE) is activated or deactivated in response to changes in the impedance.
