Positive feedback is a typical technique for distributing hysteresis around a comparator, provided that you have a resistive path between the comparator's output and the noninverting input. Positive ...

Fig 1. The traditional window comparator with a single op amp has interactions between the output and the reference voltage that creates uncertainty in its hysteresis window width. Fig 2. Adding a ...

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, ...

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...

A custom comparator IC that has fast response time and hysteresis protects a car's engine control unit from failures on monitored peripherals that create high current conditions. In most modern cars, ...
