Abstract
The present description relates to an electronic circuit comprising a first circuit configured to generate, based on a first periodic analog signal, a plurality of second signals having offset voltage levels, a second circuit configured to generate third periodic digital signals according to respective crossings, by the second signals, of at least one threshold, and a third circuit configured to determine an amplitude range in which the first periodic analog signal is located, according to a number of the third periodic digital signals.
