An example is the comparator which takes in a continuous range of voltage but only outputs one of two levels as in a digital circuit. Source: Internet
A dedicated voltage comparator may also contain additional features such as an accurate, internal voltage reference, an adjustable hysteresis and a clock gated input. Source: Internet
Consequently, an op-amp makes a sloppy comparator with propagation delays that can be as long as tens of microseconds. Source: Internet
Add an Is() comparator for checking identity, instead of equality. Source: Internet
A special advantage of the ramp-compare system is that comparing a second signal just requires another comparator, and another register to store the voltage value. Source: Internet
