Hi Ken, As I increased the max sidebands from 1000 to 2000, the total noise power nearly doubled. Do the simulations require such a high number of sidebands? Moreover, I had tested the PNOISE analysis on a simple RC circuit with a switch, and what I observed is that depending on the bandwidth of the circuit, there are cases where the PNOISE analysis significantly overestimates (double) as I keep increasing the max sidebands for a few cases. This happened especially in the case where the load capacitor was very small ~10fF. Whereas, for a few cases of the circuit bandwidth, the analysis does saturate to the theoretical value as mentioned in the documentations. Does the bandwidth of the circuit under test need to be higher for the PNoise analysis to work? Thanks!
