NMOSFET parameter extraction

  1. Hey! I'm doing a lab assignment and need some guidance.

    i have measurement with L=1μmeter and w=10μmeter, but the id data is normalized to w=1μmeter, what does it mean?

    do I need to get Ids "un-normalized" for extraction, like Ids*1e-6= new Ids

    the second question is about low-field mobility, does the low-field mobility μ0 equal for all NMOSFETs? the BSIM guide Iam using have default value is 670 cm^2/Vsec for NMOSFET. but the extracted value is like 200cm^2/Vsec, I'm confused.

    I dont know if this is the right sub-forum for posting those questions, please moderators change it to appropriate sub-forum if needed.

    Thanks in advance

    I'm sorry you are not finding help at the moment. Is there any additional information you can share with us?
  4. The general MOSFET equation is Id = mu Cox W/L ((Vgs-Vth) Vds - Vds^2/2). This is the W/L they are referring to.
