    I have some questions about mosfet parameters:
    1) Threshold Voltage:depends on channel length L (with a fixed process
    technology)? If the same process technology is used, threshold voltage
    changes with L or not?
    2)channel length modulation: if the same process technology and the
    same L are used, modulation parameter changes with W or not?
    3)electron mobility: I understand electron mobility relationship with
    L, but i don't understand its relationship with W....can you help me?

    I suggest reading the book. ;-)

    Most of the time W just scales, but I think with channel length
    modulation, the LDD has a W effect.
