I am studying transformers and have learned that core loss happens due to eddy current and hysteresis loss. Below, I provide the equivalent circuit for a transformer. Here, $$R_c$$ represents the ...

Assume such a circuit: Why should I use a schmitt trigger NOT and not a normal one? If I am not mistaken, schmitt trigger turns a hypothetical input signal that varies slowly (which is not desired!) ...

This is an attempt below to make a hysteresis detection from a sensor input. The sensor is simulated with a potentiometers on VIN for now. I am avoiding the Schmitt trigger as it does not allow ...

I built this LT431 low voltage cutoff circuit which works fine. Vin is a 0 to 4 V ascending and descending ramp, to check how it reacts. There's no load on the output. I'm having trouble adding ...

I'm working on a hysteresis mode buck converter design. In this schematic, the comparator is going to output high/low as fast as it possibly can to keep VOUT about equal to VREF. Is there some way to &...

I am building an digital input front end that is to tolerate 3-30V logic. I want to use the DAC to set a trigger threshold that will be half of the logic voltage - e.g. 12V with 24V logic. ...

When the NTC hits 80°C, the comparator will output LOW signal, but it will only be HIGH if only the NTC hit 75°C. So before the NTC hit 80°C, the circuit will work as intended. But the problem is when ...

I know this can probably be solved with some KVL but I think the theory is what is preventing me from figuring this out. I added a picture of my comparator setup below and I am trying to figure out ...
