WebApr 9, 2024 · For AC analysis, the value of AC is used as the amplitude of the source at the analysis frequency. For all the sources you don't fill in a value, 0V or 0A is used. So, all sources are applied, either with the zero value or the user entered value. What do you want to achieve with the AC analysis? WebMar 8, 2024 · 1 Answer. Sorted by: 3. Obviously, B1 has no return path. That arrow on top is ground but it's a different node than the ground you use on the bottom of the schematic. Change the arrow type ground on top (COM) to the closed triangle type ground (node 0) and you'll be OK. Share.
