Hello everyone, another problem with the simulation. I would like to simulate switching a switch to see the phase change on a circuit with an OPAMP. I have defined a sinusoidal input generator at 1Khz and 50mV signal V1. On the negative input of the OPAmp I want to simulate the grounding via the SW1 here is the diagram:
I tried to add the .model line but it doesn’t change anything! (Now is comment by #)
Here the out simulation :
the I get an error message I don’t understand :
Thanks to help !
