The gain of a typical comparator is approximately equal to
A) unity 1).
B) 3 dB.
C) the open-loop voltage gain AOL) of its op-amp.
D) 0 dB.

Question

Quizplus · Accepted Answer

Comparators are designed to compare two voltages and output a digital signal indicating which is higher. They typically utilize the open-loop configuration of an operational amplifier (op-amp), where the gain is very high (ideally infinite). Therefore, the gain of a typical comparator is approximately equal to the open-loop voltage gain (AOL) of its op-amp.
