Zusammenfassung:A system may include a passive floating attenuator configured to receive an analog physical quantity and attenuate the analog physical quantity to a floating attenuated signal defined by voltage nodes other than the voltage nodes of the analog physical quantity, an anti-aliasing filter configured to filter the floating attenuated signal to generate a filtered attenuated signal, and a switched-capacitor sampling circuit comprising a plurality of switches configured to sample the filtered attenuated signal.
