Electronic starter-alternators power hybrid vehicles
Design How-To  
7/8/2004   Post a comment
The integrated starter-alternator saves auto power by using the alternator as a starter motor. Combining these two functions into a fully reversible electrical machine allows motorists to cut off the engine when the car sits at a traffic light, counting on the alternator to make it jump as soon as we step on the accelerator. International Rectifier's engineers give details.

Software aids A/D converter performance modeling
News & Analysis  
7/7/2004   Post a comment
Converter modeling has often been overlooked, omitted, or done using an ideal data converter model. With more and more systems using mixed signal technology, the importance of system modeling is ever increasing. This, coupled with shortened design cycles and pressure for first pass success, drives the continuing importance of complete system modeling. Analog Devices' engineers describe a simulation program that may provide an answer this need.
Active termination reduces high-speed interface loss
News & Analysis  
7/7/2004   Post a comment
When the Characteristic Impedance is not correctly matched at the drive, and the receiver ends, not all of the signal energy is delivered to the load, writes Andy Fewster in the July Planet Analog magazine folio. Ordinarily, the physical geometry of the conductors and insulation, determines the "Characteristic Impedance" of the transmission line. But active termination techniques can satisfy the requirements for professional audio and video applications.
