Amplification circuit with operation point feedback function includes power transistor and emitter follower, in which operation point is determined based on signal fed into power transistor and directly connected to load

摘要

The circuit produces an output signal using the characteristics of a power transistor and an emitter follower. An operation point is determined based on the signal fed into the power transistor regardless of the polarization of its base. The operation point is linear and linked to the output, and has a mass level for direct connection to a load.
