4. Conducted EMC susceptibility model for CI 555 and MCU 68000

The EMC susceptibility of our circuit depends essentially on the susceptibilities of the active MOSFET components and the two ICs under attack from the sources previously analyzed. Quantifying this susceptibility requires the definition of observable parameters for evaluating the SoF of each component.

4.1 Observable parameter for SI analysis

The observable parameter of our circuit under test is none other than the output quantizables of the active components CI 555 and MCU 68000 during operation. Taking these ICs into account, for this case study we are interested in the Signal Integrity (SI) of the V(M 3 ) and V(M 6 ) outputs. More analytically, the susceptibility of...
