Hi,
How do I get the impedance vs frequency (fig 2.32a) plot of page 33 of the attached in LTspice?
https://www.vicorpower.com/documents/design_guides/DG-DCM-Design-Guide-VICOR.pdf
The LTspice sim is as attached, but I cannot make it work and cannot get fig2.32a
I can get the transfer function plot (fig 2.32b), but not fig2.32a.
I am just thinking that Impedance = v/i…..and so I am trying to divide the voltage at the output of the input filter, by the current coming out of the input filter, but it is not working.
I am taking 20log(10) v/i = x Db……and trying to work back to get v/i by doing v/i = 10^(xdB/20), but it doesn’t work.
Do you know how I can get fig2.32a?
