How does a comparator op amp work

WebJan 31, 2024 · A Schmitt Trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. A Schmitt Trigger uses two input different threshold voltage level to avoid noise in the input signal. The action from this dual-threshold is known as hysteresis. WebThe comparator often stands in the shadow of its big brother, the operational amplifier (op amp). Its humble status is offset by the features which distinguish modern comparators and make them ideal for their basic task: comparing two voltages. This article explains comparator features and describes the parameters that should be considered when sel
