理想放大器的输出脉冲幅度和输入脉冲幅度成正比,即输出-输入特性呈线性关系(图1);而实际放大器的输出-输入特性与线性关系有一定偏离,存在非线性。 放大器的积分非线性L_N,定义为最大的线性偏离△V_(omax)和额定的最大线性输出V_(omax)之比的百分数,即 The ideal amplifier output pulse amplitude and the input pulse amplitude is proportional to the output - input characteristics of a linear relationship (Figure 1); the actual amplifier output - input characteristics and the linear relationship between a certain deviation, there is nonlinear. The amplifier’s integral nonlinearity L_N is defined as the percentage of the ratio of the maximum linear deviation ΔV_ (omax) to the rated maximum linear output V_ (omax), that is,
