Abstract
According to an aspect of the present invention, samples of an input signal are provided with reduced distortion, when the input signal is received from a lead terminal offering lead inductance on an input path. Such a feature is achieved by charging a energy storage element to a value proportional to the input signal using a portion of charging energy received through a path having less lead inductance compared to the path connecting the input signal to the energy storage element. Thus, the energy drawn through the lead impedance is reduced, thereby reducing the magnitude of the distortion caused.
