Class ab amplifier

The first are the classically controlled conduction angle amplifiers forming the more common amplifier classes of A, B, AB and C, which are defined by the length . The class AB push-pull output circuit is slightly less efficient than class B because it uses a small quiescent current flowing, to bias . Hence, in the class AB amplifier design each of the push-pull transistors is conducting slightly more than the half cycle of conduction in class B, but much less . So, for small signals both transistors are active, acting like a class A amplifier. ST offers the widest portfolio of class AB audio amplifiers. We take you through an alphabet soup of amplifier classes, going over the real meanings behind.

The answer is that it varies with the needs for the design. The diodes are not thermally coupled to the transistors, but this is mostly a class B amp, so the rigk of thermal runaway is low. Another minimal transistor audio amp project. This one is a push pull design with only three transistors.
