EEVblog #941 – The Amazing Schmitt Trigger

Fundamentals Friday
What is a Schmitt trigger and how does it work?
What is hysteresis?
And how do they fix two common problems in electronics, namely slow slew rate signals on CMOS digital chip inputs causing oscillation, and noise on comparator inputs.
The issues are demonstrated first on the breadboard, then the whiteboard explanation, and then the hysteresis fix is added and demonstrated.
And how are Schmitt Triggers physically implemented in CMOS logic?
