FIELD: electronics; amplitude spectrometry, nuclear physics, medical electronics, audio engineering, and the like. SUBSTANCE: charge-sensing amplifier that can be used as preamplifier for taking signals off ionizing radiation detectors, for time measurements, and the like has series-connected first voltage and current amplifying stage 1, buffer stage 3, level shift circuit 4, second amplifier stage 5, voltage follower 6, as well as common feedback circuit 2. Current follower 7 is inserted between current supply 9 and positive feedback circuit 8 applied to it. EFFECT: enhanced voltage gain and maximized amplitude of output signal. 1 cl, 8 dwg
