Positive Feedback - Examples and Applications - In Electronics
... This reduces their gain, but improves their linearity, input impedance, output impedance, and bandwidth, and stabilises all of these parameters, including ... When an input voltage is expected to vary in an analogue way, but sharp thresholds are required for later digital processing, the Schmitt trigger circuit uses positive feedback to ensure that if ... One of the corollaries of the Schmitt trigger's use of positive feedback is that, should the input voltage move gently down again past the same threshold, the ...

Implementation - Op-amp Implementations - Non-inverting Schmitt Trigger
... It adds a part of the output voltage to the input voltage thus "helping" it during and after switching that occurs when the resulting voltage is near the ground ... voltage in respect to ground) so, the circuit does not need an amplifier with a differential input ... Since conventional op-amps have a differential input, the inverting input is grounded to make the reference point zero volts ...
Schmitt Trigger - Applications - Noise Immunity
... One application of a Schmitt trigger is to increase the noise immunity in a circuit with only a single input threshold ... With only one input threshold, a noisy input signal near that threshold could cause the output to switch rapidly back and forth from noise alone ... A noisy Schmitt Trigger input signal near one threshold can cause only one switch in output value, after which it would have to move beyond the other threshold in ...
