Abstract
A circuit and method for demodulating at least one modulated signal (e), such as a measuring signal of a sensor. The circuit comprises at least one input (1), with the signal (e) being applied to the input (1), and the input is connected to at least one switched-capacitor network which is configured to demodulate the signal. The circuit permits use even in a small available space.

A circuit for demodulating at least one modulated signal such as a measuring signal of a sensor, comprising
- at least one input to which the modulated signal may be applied, and
- at least one switched-capacitor network connected to the input for demodulating the signal.
A method of demodulating a modulated measuring signal of a sensor comprising the steps of
- applying the signal to an input of a switched-capacitor network and operating the network so as to demodulate the signal.
