SiGe gets real By Bill Schweber, Technical Editor
Long-heralded as the next great process for RF ICs, innovative SiGe parts are now available, but established processes, such as GaAs, still have a lot of life in them.

Speech recognition: It's not what you say; it's how you say it
By Nicholas Cravotta, Technical Editor
Greater available processing power and better algorithms continue to make speech recognition more viable for many real-world applications. The real advances, however, have been in how you can use speech to achieve"natural understanding."
Special-purpose SRAMs smooth the ride By Brian Dipert, Technical Editor
Data and telephone networks are experiencing more traffic of multiple types and at higher speeds with varying delivery expectations. Advanced SRAM-based memories play a big role in responding to performance and flexibility needs, and applications extend beyond the network.
RF cryptotransponder reader increases vehicle- and building-access
security Eric Perraud, Motorola
You can build a cryptotransponder reader using just two ICs. These ICs control the authentication sequence and implement an alternative demodulation scheme that overcomes a problem inherent to amplitude modulation.
