Hello, I'm trying to simulate the QUCS schematic attached to this email (the circuit is based on the operational transconductance amplifier at http://www.intersil.com/data/FN/FN475.pdf ), but my transient simulation fails with a singular Jacobian at t=0. Can anyone suggest a fix that will make the simulation work? Thanks! J.Patrick Bedell jpb...@mi... |

Works with shiftig the DC level of V1 to -.24, seems like another start value of the simulation might help... Stefan. |
