Abstract :
This paper describes the origins of one kind of the degradation of the electromagnetic immunity of microcontrollers. That immunity degradation is strongly frequency dependent. They appear like holes in immunity-frequency curve. Mechanism based on resonance in two types of current loops is introduced to explain the formation of those immunity holes. Measurement results are given to support the introduced theory.
