Abstract
A capacitive sampling circuit comprises: a first-differential-input-terminal, configured to receive a first one of a pair of differential-input-signals; a second-differential-input-terminal, configured to receive the other one of the pair of differential-input-signals; a capacitive-circuit-output-terminal, configured to provide a sampled-output-signal; a plurality of first-sampling-capacitors, each having a first-plate and a second-plate; a plurality of reference-voltage-terminals, each configured to receive a respective reference-voltage; and a first-capacitor-first-plate-switching-block configured to selectively connect the first-plate of each of the plurality of first-sampling-capacitors to either: (i) the first-differential-input-terminal; or (ii) a respective one of the plurality of reference-voltage-terminals; and a first-capacitor-second-plate-switch, configured to selectively connect or disconnect the second-plate of each of the plurality of first-sampling-capacitors to the second-differential-input-terminal.
