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 ...

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 ...

Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

The ongoing need for intra-circuit interface and limited-functions ICs. How small analog ICs can enable critical transitions and meet specialty roles. In a hard-to-articulate way, it’s somewhat ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...
