Low power voltage amplifier, especially for an X- or gamma ray detector, has a MOS transistor with current generators and capacitors connected to its drain and source

摘要

Amplifier comprises: a transistor (M1), a first current generator (I1), which supplies the drain of the transistor, a second current generator (I0), which charges the transistor source, and whose output current amplitude is approximately equal to that delivered by the first current generator, a first capacitor (C1) connected to the transistor drain and a second capacitor (C0) connected to the transistor source. The invention also relates to a corresponding X- or gamma-photon detector with an inventive voltage amplifier.
