    Guys plz help:confused::-

    Given incremental voltage gain Av= -gm*Rd
    prove that largest negative output signal peak that is acheivable with the transistor remaining in saturation is

    vo=(Vds - Vov)/(1+1/Av)

    Vov = Vgs - Vt

    Vt = threshold voltage

    (This is Problem no 4.53 in Microelectronic Circuits by Sedra and Smith)

    heres the complete problem......

    I think i have solved it but i want to clarify some conceptual doubts.....i.e exactly what are the limiting factors which determine the maximum allowed signal signal swing......





    thnx
