Hello John,

I think you need to be more specific regarding the measurements you want to perform and your setup. The Keithley 4200 can be equipped with many different measurement cards.

Hi Karsten,

                  I have a very basic 4200SCS with 3 SMUs and only IV sweeping and sampling measurements possible.

Thanks and Regards,

Rohit John

I have a work use Keithley 4200 test system to measure Inverter, I recommand you here.

Wang, Jiabin, et al. "Low-Voltage Unipolar Inverter based on Top-Gate Electric-Double-Layer Thin Film Transistors Gated by Silica Proton Conductor." IEEE Electron Device Letters (2017).

Thank You. I will go through the paper and revert.

MeasurING a pseudo-NMOS inverter :One SMU supplys the constant dc output voltage (Vdd) at load end ,just as from 3V to 3V.Another SMU supplys sweeping voltage at GAT , just as from 0V to 3V. At last one SMU seting to current source,from 0A to 0A, to measure output voltage(Vout).

Thanks a lot Zidong. Have you measured ring ocillator as well?

Measuring ring ocillator just need two SMU : One SMU supplys the constant dc output voltage (Vdd) , and the other seting to current source, to measure output voltage(Vout).
