Discrete Class AB Transistor Audio Power Amplifier Circuit Diagram. This is a class AB transistor power amplifier. It is a simple amplifier to build, uses standard parts and is stable and reliable. The entire circuit utilizes commonly available components and may be simply built over a general-purpose board. But this amplifier has very good sound quality.

Class AB power amplifier; the amplifier relatively free from noise by making the signal waveform out of the region between 0v to 0.6v where the transistor’s input characteristic is non-linear. Push-pull Class B amplifiers made with BJTs can be constructed using a NPN transistor for one element and a PNP transistor for the other element or with two of the same type of transistor. The NPN/PNP design is often called complementary , and requires the use of two complementary transistors that are well matched in their I C vs. V BE characteristics. The class AB operated amplifier is commonly used as a push-pull amplifier to overcome a side effect of class B operation called crossover distortion. Class B Amplifier Operation Amplifiers biased so that collector current is cut off during one-half of the input signal are classified class B. Class AB and Class C Power Amplifiers - The class A and class B amplifier so far discussed has got few limitations.

2018-08-13 A Class-AB audio amplifier involves three stages: Input stage; Voltage Amplification Stage; Output stage. And the design of each stage requires: Basic circuit theory, Transistor-based amplifier design, Filter design, And even a very basic understanding of feedback theory. So, as you can see, a Class AB audio amplifier is not a "how can I design one?" thing. Class AB amplifier is an amplifier configuration that stands somewhere between Class A and Class B configurations. A small diode biasing voltage keeps the output transistors ON even if … Class AB Power Amplifiers The class AB push-pull output circuit is slightly less efficient than class B because it uses a small quiescent current flowing, to bias the transistors just above cut off as shown in Fig. 5.5.1, but the crossover distortion created by the non-linear section of the transistor’s input characteristic curve, near to cut off in class B is overcome. 2011-08-12 The Class AB circuit, over most of its input signal range, operates as if the Q N or Q P transistor is conducting and the Q P or Q N transistor is cut off.

20. Nonetheless, class B amplifier presents the advantage over the class A to be more efficient with a theoretical maximum efficiency of η max =78.5 %. The efficiency observed on real configurations however does not exceed 70 %. Class AB Amplifier. As the name refers to, class AB amplifier behaves as a combination of class A and class B amplifiers. In this class the transistor can be used as a switch.
