Abstract – This presentation will describe the latest challenges in transmitting electronic information at ever faster speeds while at the same time reducing the power consumed. This exciting new area of engineering is called Signal Integrity and Power Integrity. Signal Integrity enables today's computers to send trillions of ones and zeroes in a matter of seconds along a physical channel to a receiver. Power Integrity ensures that no matter how fast and how many ones and zeroes are switching they will all get enough power to switch states. A final example will show how this new area of engineering could have prevented the failure of the first transatlantic telegraph cable in 1865 and how far we have come since then.

Heidi Langeberg Barnes is the World Wide Application Engineer for High Speed Digital applications in the EEsof EDA Group of Keysight Technologies. Her professional experience includes more than 6 years in signal integrity for Automated Test Equipment load boards for Verigy and Advantest, 7 years in RF/Microwave microcircuit packaging for Agilent Technologies, 10 years in hydrogen fire and gas detection for rocket engine testing at NASA Stennis Space Center, and thin film solar cell design with Arco Solar. She holds 5 patents, is a recipient of the NASA Silver Snoopy Award, and has a Bachelor of Science degree in electrical engineering from the California Institute of Technology. She grew up locally in Sebastopol and discovered engineering through her high school summer intern jobs with Hewlett- Packard.
