On-Chip Techniques for Electromagnetic Interference (EMI) reduction

Electromagnetic Interference (EMI) in Power Supplies

Increasing power density, faster switching and higher currents forces designers to spend more time both considering the effects of electromagnetic interference (EMI) and debugging a design that has EMI problems but is otherwise complete. This paper explains the different types of EMI and their coupling mechanisms and the existing EMI regulations. The most frequent noise sources, transmission pa...

Power Reduction Techniques for Networks-on-Chip

Modern Network-on-Chip (NoC) links consume a significant fraction of the total NoC power, e.g., one study has shown that they consume up to 60% of total power and that this fraction is apparently growing. We present two algorithms for power reduction in NoC links. We first present Parity Routing (PaR), a novel method to add redundant parity information to packets, while minimizing the number of...

Experimental Study of Electromagnetic Interference (EMI) on PCBs and Cables enclosed in Complex Structures

Comparison among emission and susceptibility reduction techniques for electromagnetic interference in digital integrated circuits

This paper presents a comparative study of susceptibility reduction techniques for electromagnetic interference (EMI) in digital integrated circuits (ICs). Both direct power injection (DPI) and very-fast transmission-line pulsing (VF-TLP) methods are used to inject interference into the substrate of a single test chip. This IC is built around six functionally identical cores, differing only by ...

EMI Spy: Harnessing electromagnetic interference for low- cost, rapid prototyping of proxemic interaction Citation

We present a wearable system that uses ambient electromagnetic interference (EMI) as a signature to identify electronic devices and support proxemic interaction. We designed a low cost tool, called EMI Spy, and a software environment for rapid deployment and evaluation of ambient EMI-based interactive infrastructure. EMI Spy captures electromagnetic interference and delivers the signal to a use...
