Emitter follower output stage
WebThe image shows a typical class-B emitter-follower complementary output stage. Under no signal conditions, the output is exactly midway between the supplies (i.e., at 0 V). When this is the case, the base-emitter bias of both the transistors is zero, so they are in the cut-off region where the transistors are not conducting.. Consider a positive-going swing: As … WebThus it is instructive to measure the emitter follower output impedance. Materials: 1 – 4.7KΩ Resistor 1 – 10KΩ Resistor 1 – small signal NPN transistor ( Q 1 2N3904) Directions: ... If the output stage of an amplifier …
