COMPARATOR AND ANALOG/DIGITAL CONVERTER
Document Type and Number:
WIPO Patent Application WO/2010/064338
Kind Code:
A1
Abstract:
The operating speed is improved while increases in the power consumption are suppressed. A comparator is comprised of a comparison unit which outputs the comparison result of one voltage of the input differential signal and the other voltage; a first positive feedback unit which operates synchronously with a first clock signal, amplifies the comparison result from the comparison unit, and outputs the result to an output node pair; and a second positive feedback unit which operates synchronously with a second clock signal and provides positive feedback to the output node pair.
