New developments in electronics manufacturing are increasingly dominated by the requirements of EMC today. Considerable follow-up costs in product development are caused due to the failure of electronic modules in EMC compliance tests. The integrated circuits that are used in an electronic system are critical for its EMC performance as a whole. ICs are often responsible for interference emissions or immunity weak points and it is difficult to gain control of them in such cases.
Imagine for a moment that you are trying out a brand new car: you slide into one of the ergonomic seats, start the engine and, to make things perfect, would like to listen to some music. However when you switch this on, you suddenly notice interesting side effects. The light comes on in the passenger compartment, for example. Or the radio starts whistling and whimpering.
