What is the problem in my circuit? I tried changing the voltages but its no use. I made the same circuit that was working but it’s not working now. What is wrong with it? I’d be grateful for your help.
I keep getting singular matrix: check node v1 branch
gmin=0.001 errors. Only one opamp circuit works but 4 of them not.
I have a strong suspicion that you are not using Qspice!
