The amplifier is extensively used in equipment for research work in nuclear physics. The amplifier is designed mainly for amplification of a part of a spectrum of pulses with a statistical amplitude distribution, the amplification beginning from a certain amplitude threshold. The article outlines the calculation of the amplification coefficient of the amplifier, the maximum input signal, and the transient characteristics and discusses the improved linearity of the initial portion of the amplifier’s transfer characteristic. The improvement was obtained with the “shifting threshold” and by nonlinear feedback.
