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 ...
Analog comparators are always in the shadow of their more popular cousin, the ubiquitous op amp. Designers can draw on a wealth of application notes for op amps, but not so for comparators. One ...
