Abstract
The invention provides a circuit configuration for demodulating a voltage that is ASK modulated by altering the amplitude between a low level and a high level. In this case, a first and a second charging circuit each produce a charging voltage and decoupling device decouples the first charging circuit when there is a prescribed ratio between the charging voltage of the second charging circuit and an input voltage for the rectifier circuit.
