Active inductor is a single port device.How can I connect the output port and do PSS analysis to obtain Total harmnic distortion Vs input power to characterise linearity.In the attachment I ahve shown the input port is connected and input impedance is found to be inductive.Since its a feedback arrangement i cant figure out how to connect output port to check linearity.
 

Can you understand "port" correctly ?
It defines available power and load circuit by port resistance.

Why do you require output port ?

Show me your definition of THD(Totak Harmonic Distortion).

Input and output share same terminal.

And why do you need to use port as input ?

Again.

Hi


I wish to obtain plot HD3 vs Input power.I did PSS.I selected option power in mainform as shown in attachment.In the field to select harmonic I selected 3 rd harmonic and fundamental.Ploted in db Vs input power.Since Hd3=3Rd harmonic /Fundamenatl harmonic power.I subtracted fundamental harmonic power from 3rd harmonic power.Is it the method to obtain HD3 from pss analysis.Since I am not sure the method is correct.i ploted TOTAL HARMONIC DISTORTION THD as well.
