HIGH-SPEED HALF-FLASH TYPE ANALOG/DIGITAL CONVERTER

摘要

An analog/digital converter supplying logic words constituted by P high order bits and Q low order bits, comprises: a divider (2), 2P high weight comparators (5), 2Q low weight comparators (11), and a selector (14). The high weight comparators have their second inputs (E21) enabled by the clock signal (H) and their first inputs (E11) enabled by the reverse clock signal (H*). The low weight comparators have their first inputs (E12) enabled by the reverse clock signal (H*) and their second inputs (E22) enabled by the clock signal (H).
