Comparators are one of the basic building blocks of analog and mixed-signal designs, providing one small but critical function, as their name indicates. Their role is often to be a “simple” safety ...
This application note describes comparator features and specifications as well as the differences between comparators and op amps. It also includes circuits that combine comparators and an internal ...
Low-power high-speed CMOS comparators and analog-to-digital converters (ADCs) play a pivotal role in modern electronics, from data-intensive computing systems to precision biomedical instrumentation.
EDN: Improved comparators distinguish between A = B = 0 and A = B = 1 states to enable better designs
Traditional digital comparator ICs are electronic analogs of mechanical lever scales. Like their mechanical counterparts, they compare two logical signals and produce an output (typically a voltage ...

How exactly does a comparator work? Comparators have many uses and its concept is not too hard to grasp. What I don't understand however is how exactly it compares two voltages. How does it know ...
The comparator's very low output impedance in the low state isolates R from the pull-up resistor (reference designators - !). When the output is high, the current path through the output stage is an open circuit.
