Hi,
After running "hb simulation", when I plot a spectrum it shows multiple values at one frequency and Cadence calculator uses 2nd peak value instead of 1st peak value.
in attached figure, two different values at 1MHz, 1st peak=406.35uV and 2nd peak value=269.833uV and Cadence calculator uses 2nd peak value.
1) which value I can trust in this case? and why does calculator use 2nd peak value instead of 1st peak value?
2) in Direct Plot Form, when "frequency" is selected in sweep section it shows different peak value from "spectrum" peak value.
in figure below, peak value from "spectrum" plot is 406uV at 1MHz and peak value from "frequency" plot is 657uV.
What is the difference of these two values?
Thank you.
