Quasi Complementary Push Pull Amplifier: In practical power amplifier circuits, it is preferable to employ NPN transistors for both high-current output devices. As the push-pull connection needs complementary devices, a PNP high power transistor is…
Complementary Symmetry Push Pull Amplifier: The use of transformers, at input as well as at output ends, in the push-pull amplifier shown in Fig. 17.25 makes it bulky and expensive especially in this age of…
Phase Splitter Circuit for Push Pull Power Amplifiers (or Phase Inverter): In a push-pull amplifier circuit an input transformer is used to provide the polarity inversion between the two input signals to the push-pull circuit,…
Class AB Push Pull Amplifier - Circuit Diagram, Operation and Drawbacks: The basic circuit of class AB push-pull amplifier is the same as that of class A push-pull amplifier shown in Fig. 17.25 except that…
What is Crossover Distortion and how to eliminate it? In addition to the distortion introduced due to the nonlinearity of the collector characteristics and due to non-matching of the two transistors, there is one more…
Class B Push Pull Amplifier - Circuit Diagram, Operation and Derivation: The circuitry for the Class B Push Pull Amplifier operation is the same as that for the class A operation except that the devices…
Class A Push Pull Amplifier - Working Principle, Advantages & Disadvantages: A Class A Push Pull Amplifier circuit is shown in Fig. 17.25. By Class A Push Pull Amplifier means that current flows in the…
Push Pull Amplifier - Circuit Diagram and its Workings: As we know already that, double-ended or push pull amplifiers makes use of two identical transistors in a single stage. It consists of two loops in which the…
Class D Power Amplifiers - Circuit Diagram, Operation and Applications: Historically, audio amplifiers have been configured as class A, class B or class AB and the art of design is well known. Also well known…
Class AB Power Amplifier Working Principle: In class AB power amplifier, the biasing circuit is so adjusted that the operating point Q lies near the cutoff voltage. During a small portion of negative half cycle…
