A method of amplification and shaping of analog signals produced by a large-capacitance signal source is proposed. This method is optimized for reaching the highest signal/noise ratio, and, along with that, it allows for recognizing signals that arrive with a small time interval. An amplifying channel is designed that implements the proposed method. This channel is purposed for amplification of avalanche photodiode signals in detectors based of fast scintillators. The structure of the amplifying channel, the principle of recovering the shape of the input signal, and the basic circuit design solutions used in the developed amplifier are described.
