In this article, the influence of the noise component of the aperture uncertainty on the dynamic range of the sample-and-hold circuit (S/H circuit) is considered. For this purpose, a mathematical model of the S/H circuit is constructed, which is presented in the form of an ideal sampler, at the input of which a functional block is placed that simulates distortions of the sampled oscillation in the real S/H circuit. An analytical expression is obtained to show that the noise component of the aperture uncertainty generates frequency distortions of the input signal and additional noise, the properties of which are determined by the characteristics of the aperture uncertainty and the sampled oscillation.
