This project was a sort of challenge: designing an audio amplifier capable of delivering a decent output power with a minimum parts count, without sacrificing quality. The Power Amplifier section ...

Peachtree Audio’s GaN400 stereo power amp ($3,000) blazes new trails for Class D amplification. The amp uses cutting-edge GaNFET transistors in its output stage, delivering a massive 400wpc! Read on.

This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

Back in the day (1970s), audio amplifiers like the Phase Linear 700 were designed with discrete power-transistor components. Huge audio power transistors like the 2N3055 and others back then were ...

GaN Systems is claiming up to 96% power efficiency from a 200 + 200W (8Ω) Class-D stereo amplifier built around its gallium nitride power transistors. THD+N is under 0.03%, with further optimisation ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Audio amplifier products are becoming more and more advanced in ...

Imec researchers have set a new benchmark in RF transistor performance for mobile applications. They present a gallium nitride (GaN) MOSHEMT (metal-oxide-semiconductor high-electron-mobility ...

Engineers have now achieved a breakthrough with transistors based on gallium oxide (beta-Ga2O3). The newly developed beta-Ga2O3-MOSFETs (metal-oxide-semiconductor field-effect transistor) provide a ...
