8 Bit, 200 MHz BiCMOS Comparator.

摘要

A BiCMOS comparator intended for use in low-power, high-speed analog-to-digital conversion systems operating at video frequencies and above is described. An experimental version of the comparator integrated in a 1 micro BiCMOS technology performs comparisons at rates up to 200 MHz. The circuit dissipates 1.6 mW at the maximum clock rate while operating from a single +5 V supply. The full scale input range is 1.5 V, and the measured maximum input offset is 2.1 mV for a common-mode input voltage of 1 V. Reprints. (RRH)
