Lucent Technologies Unveils Its Young Stability Curve Design Tool at Wescon 2000

Lucent Technologies (Dallas, TX) unveiled the Young Stability Curve at Wescon 2000. The Young Stability Curve is a new graphical design tool that quickly verifies product quality and reduces the time it takes to get a product out of the laboratory and into the marketplace. It works with all products and processes that contain a control system. The Young Stability Curve follows the Nyquist Curve, which was developed in 1932, as well as the Bode Plot Method, developed in 1940. It also follows the more recent Stable Operating contour plot, developed five years ago by Bell Labs Design.

Evidence of the time improvements embodied in the Young Stability Curve is clear when it is compared to the Bode Plot Method. The Bode Plot Method took three weeks to solve a simple equation; the Young Stability Curve requires half a week.

"While more complex problems took up to three months with the Bode Plot Method, the Young Stability Curve pares the time down to just one and a half weeks. A designer simply plots their load information onto a Young Curve, which yields a quick measure of stability," said Chris Young, leader of the Bell Labs team responsible for developing the new tool. "Not only does the Young Curve help you design a particular power supply into your system, it also helps you determine the best power supply in terms of stability, output impedance, crossover frequency, regulation and audio susceptibility all with a single tool."
