I have some problem in simulating this opamp in Altium pspice.
In the past i thought this model worked but there seems to be a problem in it.
I get an error message:
Source Message Time Date No.
XSpice singular matrix: check nodes e39\xu1#branch and e42\xu1#branch
This causes the iteration to hit the limits without results during Simulation.
I need this model for stability analysis of a precision current source I am debugging.
I tried the tina model in TiNa and there it works. But that is a different spice dialect.
We are standardized on Altium spice and thi sis quite a problem at the moment.
Simulation in tina s no option because the FET I use(IRLL110PbF)is not in the tina library.
Any solution?
