FET I-V characterization

[Code]

Hi, I was requested to setup I-V measurements for organic thin film transistors. I have an Agilent E3631a triple output power supply and Keithley 485 picoammeter at my hand. But I need a labview program that can take output characteristics (sweep Vds at each Vgs level) and transfer characteristics (sweep Vgs at constant Vds). Does anyone have an example program that do the I-V measurements for FETs? It can be done with HP semiconductor analyzer. But I want to have a cheaper setup in the lab. If anyone have labview programs that do I-V measurements for MOSFET, it would be great. Thanks.

Here is an tutorial on measuring NMOS characteristics with NI's hardware and DMM, but it also give general information on how to construct the test. Take a look at the code and it shows how to analyze the raw data collected from hardware and plot them.

For data collecting part, we do have instrument drivers for both of your instruments. All the functionality are written into these drivers so all you need is to configure the hardware for your application needs.
