Opamp hysteresis circuit
Did you know?
In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a digital output signal. The circuit is named a trigger because the output retains its value until the input changes sufficiently to trigger a change. In the non-inv… WebThis circuit is a slightly modified version of the circuit of Figure (13) (Inverting and non-inverting inputs). Figure 13- Inverting and non-inverting inputs The only change we have made is to include resistors between …
Webcircuits require external compensation to restore stability. Output capacitance comes in the form of some kind of load—a cable, converter-input capacitance, or filter capacitance—and reduces stability in buffer configurations.
