A circuit for processing an input-signal voltage comprises a first comparator comprising a first-comparator sense node and a reference capacitance that is coupled to the first-comparator sense node, a second comparator comprising a second-comparator sense node, and a comparator select switch coupled between a path input terminal of the circuit and the first-comparator sense node and the second-comparator sense node. A method of processing at least one input-signal voltage using at least one associated threshold voltage in a circuit, wherein a plurality of comparators comprises more comparators than there are path input terminals coupled to path output terminals, comprises selectively making a coupling via one comparator of two comparators provided in parallel to form a coupling path from the path input terminal to an associated path output terminal, while breaking the coupling via the other comparator.
