Abstract
To understand the frequency response of the immunity of complex integrated circuits and to classify the immunity over a wide frequency range, this chapter developed a set of critical features for the immunity. A circuit model of the propagation network of the microcontroller system was established to simulate the immunity of microcontrollers against sinusoidal disturbance ranging from kHz to GHz on the supply pins. Critical features were defined according to the geometry of the simulated immunity curve. The origins of those features were investigated by checking the relationship between the feature positions and circuit components. The existence of those critical features was confirmed with immunity measurements. The defined set of critical features gives a valuable approach to characterize the immunity of complex integrated circuits over a wider frequency range.
