    hallo>>^_^
    i really dont have that acknowledgment in multisim.. and i have to do somthing on it but i dont know how to start:confused::confused:

    design a CMOS oprational amplifier to meet the following spacification:-
    VDD=-VSS=2
    Vicm(max)=2.5v
    Vicm(min)=1v
    Vout(max)=2v
    Vout(min)=2v
    GB=50MHz
    SR=+/-10v/micro s
    phase margin =60 degree for CL=10pF


    and i have Multisim 8 ...
    my best regards ....​

    Thank you kahafeez … I actually start to draw two stage CMOS Op Am … but there are some part I don’t know how to do it … such as Iref, + and – as can be seen from figure below. Also how I can find phase margin and other thing (VDD=-VSS=2
    Vicm(max)=2.5v
    Vicm(min)=1v
    Vout(max)=2v
    Vout(min)=2v )

    Plz help me out to finish from this problem ….^_^
