Measuring Class-D Amplifiers for Audio Speaker Overstress Testing
نویسنده
چکیده
Determining if audio speaker limitations are violated can be challenging when using Class-D amplifiers. To obtain valid results, it is necessary to carefully analyze and interpret the switching behavior of the output signals . Filter-free Class-D amplifiers further complicate measurement because they do not require an output filter and the speaker can be connected directly to the amplifier output terminals. The following information explains the methods to obtain the correct data for determining if a speaker’s limitations will be exceeded.

THD Analysis in Closed-Loop Analog PWM Class-D Amplifiers
In this paper, we investigate the parameters affecting Total Harmonic Distortion (THD) and Power Supply Rejection Ratio (PSRR) in PWM Class D Amplifiers (CDAs) on the basis of linear models with feedback. From our mathematical analysis, we show that the THD of a PWM Class D amplifier with feedback can be improved by increasing the gain of the integrator through adding another amplifier at the o...

In this paper, the reason for the relatively high distortion level of conventional class-D audio amplifiers is discussed. It is pointed out that the classical approach is insufficient for high performance applications. Therefore the importance of the matching between modulation and demodulation is demonstrated by simulation. 1. THE CLASS-D-AUDIO AMPLIFIER The concept of class-D amplifiers was i...
