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.

Don't use Direct Plot of Cadencec ADE, since their definitions are often wrong.

Write your own equation based on your definition.
Here use harmonic(), v(), i(), getData() functions.
