Our rst C.E. conguration is illustrated in Figure 11.17.
We have a DC source

that biases the transistor to work in its active region, a
sinusoidal voltage source
v
s
for input, a load resistor
R
L
for output, and the BJT is
a silicon npn-type with output characteristic curves as represented in Figure 11.18.
To operate in class A conditions (Section 10.2.4 in Chapter 10), we require a
Q-pointapproximately in the middle of the active region.
