WebDec 4, 2024 · Behavioural sources are very versatile, but sometimes can suffer. Using the VCCS (aka G-source) should eliminate the problem. In this case, since you are only taking a current and multiply it by a constant, you can replace B2 by a VCCS like this:. It takes the voltage across R3, divides it by its value (1/16k), and then multiplies it by some constant … WebAnswer: I have seen this occur when combinations of components give both very small and very long time constants within the same analysis. So if a model has say an RC combination with a very small time-constant then the time step has to be made very small to track changes in these components. If ...
