Title:
LOW-CONSUMPTION VOLTAGE AMPLIFIER
Document Type and Number:
WIPO Patent Application WO2005011104
Kind Code:
A3
Abstract:
The invention relates to a low-consumption voltage amplifier. Said amplifier comprises a transistor (M1), a first current generator (I1), supplying the transistor's (M1) drain, a second current generator (I0), charging the transistor's (M1) source, the current provided by the second current generator (I1) being substantially equal to the current provided by the first current generator (I0), a first capacitor (C1), connected to the transistor's (M1) drain and a second capacitor (C0), connected to the transistor's (M1) source. An additional field effect transistor (M3), of a type opposite to that of the first field effect transistor, is arranged between the current generator (I1) and the first field effect transistor (M1). Said invention applies more particularly to the voltage amplification of a X-ray or gamma-ray detector.
