Abstract
A digital circuit configuration for generating a pulse-width modulated signal, particularly for regulating an analog electrical variable using pulse-width modulation, is described in which an actual value of the analog variable present at the input of an A/D converter is converted to a digital output variable, the digital output variable of the A/D converter being provided or supplied to a comparator unit, which compares the output variable to an upper threshold value and to a lower threshold value; at the output of the comparator unit, a signal being present which indicates whether the output variable of the A/D converter lies above the upper threshold value or below the lower threshold value; and it being particularly provided that the output of the A/D converter is connected to a digital timer, using which the pulse-width ratio of a generated pulse-width modulated signal is settable.
