    Hi,

    I am reading Sedra Smith and I am a little troubled with why the relation of Vsb increase = Vt increase = Id increase (ed.5 P.259)

    I agree with the Vsb increase = Vt increase

    However when Vt increase should it not cause Id to decrease if Vgs remains the same?

    Thanks in advance

    In general MOSFET can have either positive, negative and zero temperature coefficient.
