I want to plot a caracteristic of input current noise [pA/√Hz] for an amplifier ( Schematic) in in ADS (Advanced Design System) software.
1. I don't know, if there is a predefined function to do this ??? how can i use it ??
2.If there is not exist what are the formula of the input referred noise current density extracted from the schematic and how can i introduce the equation de plot the input referred noise current density???
