Ern Worthman, Technology and Editorial Director For what seems like an eternity I've been hearing the vertical markets tout the virtues of voice over the Internet protocol. The first time I heard it, it was supposed to do in the Bells and obsolete long distance call charges. That was then, this is now, and VoIP hasn't gained much ground....

Fast PLL Characterization Techniques

April 29, 2004 7:15 am | Product Releases | Comments

Traditionally, PLL characterization is a long and tedious process. A novel approach using real-time analysis promises to shorten the procedure. By Thomas Elliott A critical step in the development of a mobile handset is the characterization or validation of the unit's internal PLL component....

Silicon-On-Insulator

April 29, 2004 7:15 am | Product Releases | Comments

A perspective on low-power, low-voltage supervisory circuits implemented with SOI technology. By Ondrej Subrt The magic term of SOI is attracting a lot of attention in the design of high-performance circuits. SOI offers speed, reliability and hardness beyond traditional technologies. SOI's performance parameters can be attributed largely to overall capacitance reduction as well as lower SOI device leakage....
