9.2 For the PMOS differential amplifier shown in Fig. P9.2, let
V_(tp)=-0.4V
and
k_(p)^(')(W)/(L)=5m(A)/(V^(2))
. Neglect channel-length modulation. Figure P9.2 (a) For
V_(G1)=V_(G2)=0V
, find
|V_(oV)|
and
V_(SG)
for each of
Q_(1)
and
Q_(2)
. Also find
V_(S),V_(D1),V_(D2)
, and
V_(o)
. (b) If the current source requires a minimum voltage of
0.2V
, find the input common-mode range.
