Analysis of this circuit is simplified by the fact that the output has only two states: V out low (Vol) or V out hi (Voh). In this circuit, Voh is equal to the positive supply voltage and Vol is ...

Comparators are one of the basic building blocks of analog and mixed-signal designs, providing one small but critical function, as their name indicates. Their role is often to be a “simple” safety ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) Determining if one voltage is greater than or less than another voltage is the job for a ...
