    Refer to Fig. 7: Gate charge characteristics: Consider the operation point at VGS=3V, VDS=10 V. If we assume the channel mobility ~ 200 cm^2/V*s, what do you think the channel length approximately is?

    If someone could get my on the right track that would be awesome. I am completely lost on this question as this is a bonus question so I don't have much information on this from lectures.
    I assume that I would have to use something called “Square law” but make sure it’s the case for when Vd>Vsa but not 100%.

    But I just need some guiding hand on the concepts and right direction.

    Thank you for all the help.
