Abstract (en)
[origin: WO03025515A1] The invention relates to a circuit for demodulating at least one modulated signal (e), preferably a measuring signal of a sensor, said circuit comprising at least one input (1), to which the signal (e) is applied. In order to permit an application of said circuit even with limited available space for the circuit, said demodulation circuit is designed, such that the demodulation of said signal (e) is executed by means of at least one switched-capacitor network (2), connected to said input (1). The present invention also relates to a corresponding method.
