hello, I have implemented the circuit shown in the image attached with this post. When i run the circuit it gives me and error i.e.
"ERROR -- Convergence problem in transient bias point calculation".
The simulation window shows these messages:
"ERROR -- Convergence problem in transient bias point calculation".
The simulation window shows these messages:
