Figure 1(a) shows a series fed class A amplifier circuit. In order to achieve the
maximum efficiency, the Q point must be located at the center of the DC load line as
shown in Figure 1(b). This generates the maximum output current swing of
Icmax (p – p)
RC
and the maximum output voltage swing is
VCEmax(p – p) = Vcc
Assume that the maximum input de power is
(1 Vcc
Pimax(dc) = Vcc!cQ(max)=Vcc \2° Rc.
