Abstract
A circuit device for restoring the symmetry of an analog signal originated by the reading of data from magnetic supports, including at least one differential cell multiplier whose cell includes a pair of input MOS transistors having respective conduction terminals linked together at a circuit node. Advantageously, provided in parallel with each of the cell input transistors, are a plurality of transistors individually connectable to and disconnectable from each of the input transistors by corresponding switches.
