Same as: behavioural non-inverting schmitt trigger 01 but with parameters.


Non-inverting Schmitt trigger with 0 - 5V output and voltage controlled high and low threshold levels. Input provided by behavioural 5V peak to peak 1kHz cosine voltage source with an exponential startup from a 2.5V DC offset at a time constant of 500us, hard limited at 0.5V and 4.5V.

A behavioural current source with a 1R load and a 1pF parallel capacitance is used in preference to a voltage source (with or without a series resistance/parallel capacitance to ground) because Norton equivalent circuits generally calculate faster and converge better than Thevenin equivalent sources. Band limiting behavioural sources also helps convergence.

Note that parameters can be swept! In this case it is lothresh.

Same as:

but with proper parameters.
