As electronic systems get more sophisticated, strongly heterogeneous functional blocks are required to be placed close to each other in a strictly constrained amount of space (either at board level, system-on-a-chip level, or integrated level) to fulfil the reduced requirements on the size and the costs of the desired final solution. The coexistence of such different functional blocks leads to many circuital issues. Here, the problem of electromagnetic interference (EMI) generated by a circuit and affecting nearby ones is considered. The relevance of this problem is such that, in the design of any circuit, it is mandatory to comply with a set of international regulations that limits the level of the emitted electromagnetic energy to ensure the electromagnetic compatibility (EMC) of the device with ones located in the nearby environment.
