ECE 3274 Power Amplifier Project (Push 3.1 Class-B Amplifier This lab introduces two amplifier topologies: The Class-B amplifier, and the Class-AB amplifier. The Class-B amplifier consists of two transistors in a push-pull configuration. Figure 1 shows a common configuration using a 2N3904 transistor and a 2N3906 transistor. When the amplifier is in its quiescent state, no current flows in
