For the relative amplitude of the random telegraph signal noise (RTS) in a MOS transistor ΔG/G = ΔI/I = 1/N = qgm/WlCoxI often holds with N the total number of free carriers. Here, strong deviations from this simple behaviour will be explained in terms of strategic or less strategic trap positions in a non-uniform channel. The levelling off in the 1/N dependence for extremely low N in the subthreshold region is explained via the solution of the Poisson equation showing that this phenomenon occurs for Qdepletion≥Qinversion even in a uniform channel, ignoring mobility modulation.
