ABSTRACT:
A circuit configuration for a comparator provides that first and second transistors on an input side are connected jointly by their two control terminals to a first input terminal, and that the first and second transistors have different cutoff voltages. Such a circuit configuration has the advantage that at a zero-volt input voltage, no current is consumed. The circuit configuration can be connected directly to a high-voltage supply without the aid of regulating voltages or high-precision reference voltages.
