(Credit: BYU Photo) ADC (analogue-to-digital converter) microchips change analogue inputs into digital signals are in virtually all types of electronic device we use today. Smartphone manufacturers like Apple and Samsung are constantly searching for improved ADC chips that can deliver high performance, but as efficiently as possible so that battery life can be maintained. The new BYU-developed ADC chip consumes just 21 milli-Watts of power at 10GHz for ultra-wideband wireless communications. According to the university’s Professor Wood Chiang, existing ADCs consume hundreds of milli-Watts or even Watts of power at comparable speeds.
