If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier ...

Fig 1. This shows the spectra of both waveforms when the Class D output is issuing silence (no audio, duty cycle = 50%) with a switching frequency of 333 kHz.

A simple extension of a previous class A/B differential output amp DI that creates a square-law characteristic.

Class A/B amplifiers combine the virtues of Class A and Class B designs by having one output device stay on a bit longer, while the other device takes over amplifying the other half of the audio ...

When Class B transistor amplifiers rose to prominence in the 1960s and 70s, Luxman engineers were quick to recognize the pitfalls of related switching distortion. Audiophiles know this distortion ...

Inspired by the excellent idea shown in the article “ Class AB 20-W current booster is insensitive to temperature variations ” by Jordan Dimitrov, this variation of the design shown in Figure 1 ...
