Op-amp Comparator - Basic Electronics Tutorials and Revision
The Op-amp comparator compares one analogue voltage level with another analogue voltage level, or some preset reference voltage, V REF and produces an output signal based on this voltage comparison. In other words, the op-amp voltage comparator compares the magnitudes of two voltage inputs and determines which is the largest of the two.
Comparator - Wikipedia
A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.
Voltage comparator using opamp. Inverting voltage comparator…
2011年11月25日 · Voltage comparator is a circuit which compares two voltages and switches the output to either high or low state depending upon which voltage is higher. A voltage comparator based on opamp is shown here. Fig1 shows a voltage comparator in inverting mode and Fig shows a voltage comparator in non inverting mode. Non inverting comparator.

The input offset voltage (VIO) can be defined as the differential input voltage to apply in order to be at the toggling level. Input offset voltage limits the resolution of comparators. Therefore, for very small signals (in the same order as the V IO), the comparator toggles at an undesired value or does not toggle at all. Figure 7. Voltage marking
A window comparator makes use of two comparators with different reference voltages and a common input voltage. The comparators are connected to logic in such a way that the final output logic level is asserted when the input signal falls between the …
