2-Input AND gate: Is this behaviour good...or bad in QSPICE?


This is the simulation of 2-Input AND gate. Am I doing something wrong? Is this behaviour good or bad in QSPICE? When V(in1) is high and V(in2) is high => V(out) should not be high as well?

ok. I understand from where the mistake comes…

You figured it out. The logic gates need power & ground to operate.
