8.43 Figure P8.43 shows an IC MOS amplifier formed by cascading two common-source stages. Assuming that VAn = |VAp| and that the biasing current sources have output resistances equal to those of Q1 and Q2, find an expression for the overall voltage gain in terms of gm and ro of Q1 and Q2. If Q1 and Q2 are to be operated at equal overdrive voltages, |VOV|, find the required value of |VOV| if |VA| = 4 V and the gain required is 300 V/V.
