CLASS B AMPLIFIER

CLASS B AMPLIFIER. Class B Amplifier. In class B, the transistor is biased just off. The AC signal turns the transistor on. The transistor only conducts when it is turned on by one-half of the AC cycle. In order to get a full AC cycle out of a class B amplifier, you need two transistors:.
