High Speed A/D Converter Technology Survey

Abstract

Surveyed are current and future high speed A/D technologies with potential for a significant impact on future systems. Current bipolar silicon monolithic quantizers and hybrid sample-and-hold circuits are described. The gallium arsenide integrated circuit technology, including FETs and TEDs, provides speed increases from 10 to 100. Josephson Junction devices are discussed as a technology potentially offering radical increases in sample rates and reductions in power.
