Abstract: A parallel sense amplifier includes a measuring branch for receiving an input current to be measured, a plurality of reference branches each one for receiving a reference current, and a plurality of comparators each one for comparing a voltage at a measuring node along the measuring branch with a voltage at a reference node along a corresponding reference branch; the amplifier further includes a multiple current mirror for mirroring the input current into each reference branch.
