Abstract
A circuit for processing an input-signal voltage comprises an input capacitance coupled between an input node of the circuit and a sense node of a comparator and a reference capacitance coupled to the sense node of the comparator. A method for processing an input-signal voltage comprises configuring a reference capacitance coupled to an input capacitance; during a charge phase, charging the reference capacitance to a first-level reference voltage; and, during an operative phase, setting the input capacitance to an input-signal voltage to obtain, at the sense node, a sense voltage.
