If I do a DC SWEEP of -0.5v~0.5v to a Schmitt Trigger Inverter, Why do I see
Y:VOUT
----------------------------------- \\ \\ \\
----------------------------------- x: VIN a b
(a=-0.2v, b=-0.19v)
If I dida TRANSIENT Simulation of an Inverter of question.
Y:VIN ------------------------- / \\ / \\ / \\ / \\ / \\
-----------------------------
----------------------------- x:time
Y:VOUT
-------------------------------
------------------------------- x:time \\ / \\ / \\ / \\ / -------------------------
What I want say is that the Inverter above has Hysteresis Characteristic of a Schmitt Trigger Inverter.
However, if I do a DC simulation of the same Inverter of question, (i.e. when the inverter is dc swept)
Y:VOUT
----------------------------------- \\ \\ \\
----------------------------------- x: VIN
It seems to be just a normal Inverter.
Why does this Inverter shows an Schmitt Trigger Characteristics in TRANSIENT sim, and a normal Inverter Characteristic in DC simulation?
Is this Inverter a Schmitt Trigger Inverter or a Normal Inverter?
