Side-channel attacks

A side-channel attack is a form of reverse engineering that takes advantage of the information leakage from electronic circuitry. And it is a major risk to design security.

Envelope tracking for RF power amplifiers in mobile handsets

‘Envelope tracking’ is not a new technique; it has been known about for more than 50 years. But it could greatly help the power consumption challenges once more facing mobile handset design.

Fundamentals of Signal Integrity Analysis

New to Signal Integrity analysis, or just need to brush up on the fundamentals? If so, this white paper is aimed at you. This white paper starts at the very basic, actually before the fundamentals, answering the question “What do I need to know?” The paper begins by identifying and analyzing critical nets. Next, it […]

Plane Noise Effects

High-speed digital drivers need a good source of power to produce clean, fast signals. For a driver to switch the state of a signal in tens or hundreds of picoseconds, the power plane must be able to supply significant current over a wide bandwidth. The surge in current creates voltage fluctuations in the power distribution […]

Designing a PCB for power integrity

Signal integrity (SI) issues have been around for a while, the result of ever-faster edge rates. Both SI and PI problems manifest themselves as data errors. Indeed, PI problems are often misdiagnosed as SI problems. As such, an understanding of power delivery issues is essential to the success of any board project, as is a [...]

Defeat ground bounce, far end and near end cross talk

Signal integrity guru Eric Bogatin describes some of the most effective strategies for avoiding noise Left to itself, cross talk can ruin your day. Cross talk between signal lines creates noise that erodes the noise margin. This noise may not be so great that it alone will cause a bit failure, but it can be […]

Board-level timing analysis

This paper builds on “Timing Numbers In ICX – What do we do with them?” [1]—a paper presented at the 2006 Mentor Graphics User2User conference (and now available for download at the journal’s Web site, www.edatechforum.com). The original paper focused on the need for timing analysis and the theory behind it; this paper takes a […]

Military comms system requires new tools, flow and backplane

The contributor supplies high-end military communications systems to both the US and Canadian Navies and here describes the development of a new methodology and also a new backplane for a system that is now being retrofitted onto all ships in Canada’s fleet. The project represented a tipping point. In specific terms, the changes were undertaken […]
