Abstract: A method is provided for generating a pulse signal with modulable-width pulses. A set-point signal is generated and compared with a control signal so as to produce the pulse signal. When the control signal is a two-state logical signal, a first reference voltage is taken as the set-point signal. When the control signal is a continuous analog voltage, the set-point signal is varied between the first reference voltage and a predetermined second reference voltage, which is higher than the first reference voltage. Also provided is a device for generating a pulse signal with modulable-width pulses. The device includes a set-point signal generator, a control signal generator, and a comparator that outputs the pulse signal. The set-point signal generator includes a first voltage source for generating a first reference voltage, and a second voltage source for generating a second reference voltage, which is higher than the first reference voltage. In a first operating state, the generated set-point signal varies between the two reference voltages, and in a second operating state, the first reference voltage is supplied as the set-point signal. The set-point signal generator is operated in the first operating state when the control signal generator generates a continuous analog voltage as the control signal, and in the second operating state when the control signal generator generates a two-state logical signal as the control signal.
