Abstract
Electronic circuit for the analog-to-digital conversion of the alternative current (AC) component of an analog input signal. The electronic circuit has a coupling device with an input and an output coupling device delivers at its output an analog AC signal when the analog input signal is applied to the input. An analog-to-digital converter converts the analog AC signal into a digital output signal. A feedback loop has a digital-to-analog converter for converting the digital output into an analog feedback signal, the feedback loop being coupled to the coupling device, and the feedback loop has a first feedback path comprising a switched capacitor.
