Abstract"Mobile wireless communication systems designers face the challenge of increasing the digital content of their solutions. Digital processing begins with the first analog-to-digital converter (ADC), which ideally is as close to the antenna as possible. Atpresent, however, existing ADC technology imposes significant speed, power, and precision implementation barriers. For this reason, the U.S. Air Force has challenged the technical community to develop a high-speed, low power, high-precision ADC. The AirForce requirements include 16-bit resolution, 50 MHz minimum bandwidth, 100 MSPS throughput rate, and a power dissipation of less than 100 mW. The proposer's response to this challenge is a radically new ADC technology called Peregrine. Peregrinedifferentiates itself from other ADC architectures by virtue of the fact that it is based on a number theoretic approach to ADC conversion. Peregrine data conversion is performed within independent small wordlength channels which reduce the ADC mapping toa collection of concurrent low-complexity operations. The Phase I study will research this new ADC architecture, quantifying speed and power metrics for the 16-bit, or better, CMOS design implementations required in mobile wireless applications such asGPS. When commercialized, the resulting Peregrine ADC will be embedded into high-performance wireless system-on-chip (SoC) solutions. The commercial value of the developed technology is substantial
