The Class D Audio Power Amplifier: A Review
نویسندگان
چکیده
Class D power amplifiers, one of the most critical devices for application in sound systems, face severe challenges due to increasing requirement smartphones, digital television, sound, and other terminals. The audio amplifier has developed from a transistor field-effect tube amplifier, amplifiers have made significant progress circuit technology, components, ideological understanding. stumbling blocks successful are low efficiency high distortion rate. Therefore, becoming necessary smartphones terminals their efficiency. However, switching nature intrinsic worst linearity compared linear make it hard dominate market high-quality speakers. breakthrough arrived with GaN device, which is appropriate fast-switching high-power-density electronics elements traditional Si devices, thus, reducing electronic systems’ weight, consumption, cost. allow fidelity This paper analyzes discusses topological structure characteristics makes judgment that based on future development direction amplifiers.

A Second-Order Class-D Audio Amplifier
Class-D audio amplifiers are particularly efficient, and this efficiency has led to their ubiquity in a wide range of modern electronic appliances. Their output takes the form of a high-frequency square wave whose duty cycle (ratio of on-time to off-time) is modulated at low frequency according to the audio signal. A mathematical model is developed here for a second-order class-D amplifier desi...

متن کاملA Class E Power Amplifier with Low Voltage Stress
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
