Integration of audio into portable devices such as cellphones, DVD players, laptop computer and gaming devices has increased to the point where designers are faced with squeezing more and more ...

CLASS D audio amplification is becoming the solution of choice in consumer audio, by enabling long battery life and compact dimensions. However, designers must take care to avoid complexity elsewhere ...

Class A devices feature a design in which the output stage passes current at all times, even when the input stage is idle. Class B devices do not pass current when the output device is idle. Class AB ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier configurations. This doesn’t come up as often as it used to, but it is still a good ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

Opportunities span compact, energy-efficient amplifiers for wireless devices, smart homes, consumer electronics, automotive infotainment and EVs. Semiconductor and DSP advances enable premium sound, ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...
