Automating sawtooth tuning
Length matching within a differential pair can be one of the more tedious tasks facing a PCB designer. This article describes how a team at communications and consumer electronics semiconductor company...
View ArticleMake simulation your friend
The earlier in a design cycle a decision can be made, the shorter the development time and the lower the development cost. This is probably the most important product development principle, and is...
View ArticleDesigning a PCB for power integrity
Power integrity (PI) is an increasingly complex problem in higher-end electronic product designs. A few years ago, all ICs ran at 5V; single 5V and GND layers were all you needed to deliver sufficient,...
View ArticlePlane 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...

In today’s competitive market place, companies must find new ways to differentiate their products. In response, many companies are turning to electronics to enable new innovative features. As a result,...
View ArticleFundamentals 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,...
View ArticleEnvelope tracking for RF power amplifiers in mobile handsets
Reducing the power consumption of RF power amplifiers (PAs) is a key challenge facing 3G and 4G smartphone OEMs as ever higher data rates drive network standards. RF signals using orthogonal...
View ArticleOvercoming increasing PCB complexity with automation
John Isaac In a recent survey by the Aberdeen Group, (“Why PCB Design Matters to the Executive”), 53% of electronics company respondents said that increasing PCB complexity was their main challenge as...
View ArticleConcurrent design: one team, one virtual location
As electronics design becomes more complex, it is increasingly important to find ways to enable large teams with diverse skills to work together on a project. With design schedules shrinking,...
View ArticleBetter PCB design using the fabricator’s view
PCB designers can get so deeply immersed in their work that they hardly consider manufacturing. It can be difficult to see the forest for the trees. Adopting another perspective — that of fabricating...
