A new book authored by Robert N. Buono delves deeply into Class-D amplifiers, a crucial technology in audio designs. Buono ...

They’re so simple, you can buy a class D amp chip for $3, but [George] thought that would be too easy. Instead, he built his own with an ATTiny and an H-bridge motor driver.

Figure 2: An open-loop Class D amplifier basic diagram including a nearly-lossless filter design architecture in which the only intentionally dissipative element is the speaker (Courtesy of Analog ...

Class D amplifiers are not new, but recent advances in the technology of semi-conductor devices have regenerated interest in developing them.This basic design of a class D audio power amplifier ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

Class D amplifiers maynot have much name recognition, but they're already changing the ways welisten to music, with the welcome side effect of shrinking and greeningthe world's audio hardware.

ISSCC: Class-D audio amplifier voltage-boosts its own output ISSCC, the International Solid-state circuits conference, is the IEEE’s annual showcase for all that is best in on-chip circuit design from ...

EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or ...

The DDFA architecture employs a fast and highly accurate digital feedback loop to create a Class-D audio switching amplifier that sets new standards in digital amplifier sound quality.
