    hi

    i need to calculate the Vgs and Vds and the current of the whole two transistor in three situations:

    1. cutoff

    2. saturation

    3. linear

    i found that the lower transistor is always in saturation...and i also found that for cutoff : Vgs < 2Vt

    and therefore for saturation and linear must be Vgs> 2Vt

    however i didnt find any condition on Vds and i didnt know how to find the current

    thanks
