Hi,
I am Simulating LNA S2P file in ADS using Cosimulation method. The results are in accordance with datasheet when i use ideal ground( Global schematic ground) but when i use circuit ground(local ground)the results are not good. What could be the reason?
I want to simulate the effects of local ground which will be the real practical situation.
