Editor’s note: PhD candidate, Seyyed Hossein Pishgar approached me with this paper, which I believe has some unique and creative circuitry and architectures. I have ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...

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 ...
