Comparators offer shorter delay times and a very high slew rate compared to an op amp. Despite what may appear as similarities, the two circuits are different animals with different applications.

It certainly made the analysis of these simple circuits, the comparator, the buffer amplifier, and a general non-inverting amplifier simple.

Typical propagation times for op amps used as comparators will be very slow. Since an op amp used as an open-loop comparator is always in saturation, the saturation recovery time becomes critical.

The advantages of these circuits are low-power consumption, a high degree of regularity and simplicity. In this paper, the design of a 16-bit comparator is proposed.

Over-zero voltage comparator: a typical amplitude comparison circuit with the circuit diagram and transmission characteristic curve shown in the figure.

The humble op-amp can be configured into so many circuit building blocks that it has become an indispensable tool for designers.
