Figure 9-47 Figure for Problem 9-2.
9-7 If a differential pair has 10% of its energy transformed into the common
mode when driven differentially, is 10% of its energy transformed into
the differential mode when driven commonly? Show the math to support
your answer.
9-8 Derive the ABCD matrix for the pi circuit shown in the bottom of
Table 9-2.
9-9 For the differential pair in Figure 9-49, at what frequency will the ACCM
be 100%? Assume that the effective permittivities are ε r, odd
=
3 . 5 and
ε r =
4 . 0.
