Hey! I want to design a Schmitt Trigger whose Hysteresis Voltage (Difference of 2 Thresholds) and Mid-Threshold (Average of 2 Thresholds) can be independently varied with Potentiometer as Variable Resistor or Variable Potential Divider (or as a Variable Voltage Reference directly at Inverting or Non-Inverting Terminal).
My operation is Single Supply with +24V and Ground Levels. But I would like to know for general case with dual (and unequal in magnitude) power supply.
I prefer making it with a Comparator IC with Open-Drain (can only Pull Down but not Pull Up). But I would love to know equivalent Circuit with OP-Amps.
Besides, I would love to know how to design these kind of circuit topologies myself rather than asking someone that fulfil the requirements (like the requirement of selected independent variable parameters).
Thank You!
