Abstract :
Low-cost A/D conversion requires maximum use of low-tolerance elements on a single silicon chip. This paper will describe an A/D converter, using a minimum of linear components, employing digital-phase lock-loop techniques. Input voltage is converted into a frequency whose phase is compared to that of a reference frequency.
