As a result, a small base current controls the much larger collector current. We refer to the bipolar junction transistors as small signal amplifiers because the devices require a small bias voltage to establish the Q-point--or operating point. Without the bias voltage, the transistor cannot increase the amplitude of an ac signal.3.2.2 Small-Signal Analysis ... 3.2.3 Large-Signal Operation ..... 21 3.2.4 Linearity Enhancement ... Fig. 2.4.
