How do I design a Schmitt Trigger (with op-amps) circuit with this circuit simulator?
You can easily design Schmitt Trigger (with op-amps) circuit diagrams by practising with the given circuit simulator. With this online circuit simulator, you can design and simulate your own electronic circuits.
The input is a noisy 40 Hz sine wave, shown in the first scope. The threshold is shown in the second scope. The third scope is a graph of the output versus input. Note that the threshold goes down whenever the input rises above it, and vice versa.
The two 10k resistors form a voltage divider that put the threshold voltage (the + input of the op-amp) at 5 V. But, the output of the op-amp is also connected to the threshold input through a 100k resistor. This causes the threshold to be raised or lowered slightly depending on the op-amp output.
