Design of EMI resilient automotive integrated circuits in SOI technology

Electromagnetic compatibility (EMC) problems are the third origin of redesigning integrated circuits, as they are the source of interference problems, noise emission, and sensitivity. Due to the technology trends, EMC problems also become more complicated because there are fundamental constraints due to high-speed clocks, the high number of electronic systems, chip complexity, lower supply voltage, and safety users. In this case, EMC has become a major concern for designing ICs which requires strong skills in electromagnetism, electricity, and microelectronics. This is a very vast subject and different researches have been performed in this area. Hence, several guidelines and standards have been developed including some techniques such as shielding and filtering. However, the problem is that they are concentrated on a rule-based approach and even though these rules are right, there is no guarantee that they are sufficient. So we cannot be sure that a new system will be reliable and safe or not. The goal of my Ph.D. is to find a risk-based approach for electromagnetic emission and immunity issues for designing ICs. From another point of view, up to now, the electronic devices have been evaluated just when they are new but the environmental factors including aging, vibration, and temperature or changes due to maintenance, repairs, and upgrades are not considered adequately. Moreover, different simultaneous EMC problems cannot be assessed with standards. In this thesis, I intend to rectify these shortcomings by considering the whole system over its lifecycle. To this end, I should also pass some courses to reach a correct view of the real problem which is an interdisciplinary subject. Analog and Mixed-Signal Electronics for Signal Processing, Electromagnetic Interference in Analogue and Digital Systems, and Design of Digital Integrated Circuits are scientific courses that I am supposed to follow.
