This is the circuit diagram of 2000W class AB power amplifier uses 7 pairs MJ15003 and MJ15004 transistors for the final amplification block. The circuit operated with 90V DC symmetrical (dual polarity) power supply circuit. The transistors must be mounted on heatsink to prevent the overheating...
Input clamping structure for sound quality improvement in car-radio class-AB power amplifier designA clamping circuit for a class AB amplifier includes a reference voltage circuit, four NPN Darlington transistors having inputs coupled to the reference voltage circuit, and outputs for providing four ...
Class A power amplifier is a type of power amplifier where the output transistor is ON full time and the output current flows for the entire cycle of the input wave form. Class A power amplifier is the simplest of all power amplifier configurations. They have high fidelity and are totally i...

This paper presents the design of a class-J power amplifier with a double-ended active inductor (DEAI) intended to replace the passive lumped inductor of its output-matching network. With this approach, it is possible to achieve inductance tunability, while occupying less chip area. The main fo...
Thus, there exists a need for an ultra low voltage CMOS class AB power amplifier architecture, having a common-mode feedback quiescent current control circuit. The power amplifier should also have high gain, inherent stability and simplicity of implementation which have proved difficult in the past...
