1 The MOS Cascode (Cascaded Cathode) CGCSsedr42021_0636a.jpgFigure (a) The MOS cascode amplifier. (b) The circuit prepared for small-signal analysis with various input and output resistances indicated. (c) The cascode with the output open-circuited.
2 Figure (a and b) Two equivalent circuits for the output of the cascode amplifier. Either circuit can be used to determine the gain Av = vo/vi, which is equal to Gv because Rin = ¥ and thus vi = vsig.
