8.42 Figure P8.42 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 | = 5 V and the gain required is 400 V/V.
