Answer by Circuit fantasist for Op-amp with Schottky diode
Building Schmitt triggerHere is a possible scenario for building the circuit in four steps that might help make sense of it.1.Producing V- and V+First we connect the two input stage sources through 22...

Answer by Antonio51 for Op-amp with Schottky diode
... the voltage is difference between the two inputs is constant e.g. 0.4 V, independent of the input voltages, ...Diodes are 1N4148. This is not true.Here are two examples of simulating with opamp. R1...

Answer by Spehro Pefhany for Op-amp with Schottky diode
The diodes conduct hardly at all near the switching point, which is where the two input voltages are almost equal (within a mV or so for most op-amps), so they can be ignored when analyzing the circuit...

Op-amp with Schottky diode
I'm struggling to understand what the sense is of using the two Schottky diodes in this excerpt of a circuit:I understand how a Schmitt trigger works. The diodes ensure that the voltage difference...
