(Jaren Wilkey/BYU Photo) BYU electrical and computer engineering professor Wood Chiang and a team of engineering students have created the world’s most efficient, high-speed analog-to-digital converter (ADC) microchip. ADC microchips convert analog signals to digital signals. The piece is present in almost every electronic; the faster and more efficient it works the faster it is to upload and download items and other aspects like video quality, Wi-Fi and battery life improves. Chiang and the engineering students beat the current record by a long shot. Their ADC uses only 21 milli-Watts of power at 10GHz for ultra-wideband wireless communications. In comparison, competing ADCs use hundreds of milli-Watts or even Watts of power at similar speeds. This makes their ADC faster while using less energy. Chiang is proud of the work he and his students put into this feet.
