Hello researchers please tell me regarding what the real impedance vs imaginary impedance nyquist plot of fet transistor tells.Actully I had plot the frequency analysis ( so called nyquist & bode plot) of a FET file attached but I am not able to understand that what it actually tells about my device.
Share some experimental details.
The values obtained from the equivalent circuit are not matched with the Nyquist plot. Please check.
Dear Sir
Thanks for your answer could you please tell me from where I can learn to obtained the equivalent circuit of the Nyquist plot.Because the plot i got is just a hit & trial method based on Autolab Nova software, where the software have many equivalent circuits for the plots it designed and we have to match the device under test (DUT) results with the equivalent circuits (e.g RC,RRC,RLC,RRLC etc) available in the software.
Dear Kapil,
I also agree with Sujoy, Because the Nyquist plot you obtained is equivalent to resistor in parallel to a conductor.
Please check the experimental data again
