Abstract
A current pre-amplifier with an input capable of receiving or supplying an input current with at least one pulse, wherein the pre-amplifier includes a regulated cascode stage including an input transistor and a first current generator as well as an output transistor and a second current generator. The pre-amplifier includes a detection device capable of detecting an input current pulse, and a feedback device capable of increasing the current supplied by the first and/or the second current generator during the entire detection of the input current pulse.
