The comparator is a high-gain amplifier that is used to amplify a small differential signal at its input, and drive the output to one of two output states. Figure 1 shows the basic comparator circuit, ...

Although humble in concept, today’s voltage comparators perform a simple basic task: comparing two voltages to determine which is larger. To accomplish this task, they accept two analog signals and ...

1. A conventional circuit uses a diode after the comparator to rectify the output onto C3. The circuit uses an LT1716 comparator. R2/R3 set up a 10-mV threshold to keep the output normally high, and ...
