WebStep 1: DC Biasing of Common Emitter Configuration. The purpose of biasing a circuit is to establish a proper stable dc operating point (Q-point). The dc operating point between saturation and cutoff is called the Q-point. The goal is to set the Q-point such that that it does not go into saturation or cutoff when an ac signal is applied. WebMar 17, 2015 · This may cause clipping distortions of the output signal when the follower is ac-coupled to a resistive load, for reasons which are sometimes not obvious. First, look at the simple NPN emitter ... WebSep 19, 2024 · An NPN emitter-follower is able to source current with very low impedance (since the transistor is able to raise the output voltage high very easily), but the only way it can sink current is via the emitter resistance. The statement that the circuit has an output impedance of 75Ω is dependent on how you connect the load. bowen overshot manual
