Unlike the level Vo
°
required for a passive imped-
ance, Vo
°
will be smaller than 2Vo in our case. Let
us write Vo
°
=kVo with k the matching factor vary-
ing between 1 and 2. Assuming that the current
through R3 is negligible, it comes the following re-
sistance divider:
After choosing the k factor, Rs will equal to
1/2RL(k-1).
A good impedance matching assumes:
From (eq4) and (eq5) it becomes:
By fixing an arbitrary value of R2, (eq6) gives:
Finally, the values of R2 and R3 allow us to extract
R1 from (eq1), and it comes:
with GL the required gain.
