Special Issue Information

Dear Colleagues,

Signal and power integrity (SI/PI) are essential and interlaced aspects of contemporary advanced digital and hybrid electronic system design. The correct and effective use of their rules sets not negligible challenges to design engineers in a broad range of theoretical and practical issues: the understanding of the physical mechanisms associated to the flow of currents and the delivery of electric power at the extremely high harmonics of the digital signals; the behavior of electric-to-optical (and their reverse) interfaces; the electrical behavior and modeling of the conductor, organic (inorganic) substrate or semiconductor materials; and the identification of proper figures of merit for a signal channel quantification, to name but a few examples.

The paradigm of the Artificial Intelligence and its applications to improve the quality of signals and electric power at board, package, and also die level have opened up wide fields in the research in signal and power integrity.

This Special Issue wishes to offer the opportunity to engineers and scientists to exchange state-of-the-art developments in the field of signal and power integrity applied to any kind of high-speed circuit and system, to the modeling, design, validation, and testing of electronic hardware. The topics span from the theory, algorithms, and methods to improve the accuracy, efficiency, and optimization of signal and power integrity simulations to practical applications, innovative tools, prototypes, measurement approaches, and sensors that help and support the correct and advanced SI/PI design of electronic systems and components.

With power designers always demanding for faster power switches, electromagnetic interference has become an issue of primary concern. As known, the commutation of power transistors is the main cause of the electromagnetic noise, which can be worsened by the presence of unwanted oscillations superimposed onto the switching waveforms. This work proposes a solution to mitigate the oscillations caused by the turn-on of a power transistor by exploiting its source inductance plus an external one. In this context, an optimization method is proposed to find the optimal value of the source inductance as a trade-off between oscillation damping and power dissipation. The experimental results performed on a prototyped power converter assess the proposed technique as the spectrum of the conducted emission is attenuated by 20 dB at the oscillation frequency. With respect to traditional solution based on snubbers, the proposed solution results in a similar oscillation damping, but with a 0.5% higher power efficiency. Full article
