Abstract
A method for generating a control signal after a predeterminable period of time is described. The method includes applying a voltage to an inductor at a beginning of a time measurement; and outputting, via a current threshold value detector, the control signal if a current through the inductor exceeds a predeterminable threshold value. The invention also relates to a timing circuit.
