Using a conventional comparator, you would need to place an additional high-voltage switch in series with the comparator input in order to protect it. (Part 2 of this article looks at the PWM ...

A well-known window comparator circuit uses a single op amp and has a hysteresis window that depends on R3 and the reference voltage’s input resistance, RIn . The value of RIn is: ...

Here, the reversible low power n-bit binary comparator has been designed. The two new reversible gates namely BJS and HLN gates are used to design an n-bit binary comparator.
