Comparators are used to differentiate between two different signal levels. For example, a comparator may differentiate between an over temperature and normal temperature condition. Noise or signal ...

Testing a set of analog comparators for hysteresis can be a time-consuming process. You have to accurately find the threshold voltages for numerous devices across variations in fabrication process, ...

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 ...
