- Class D Amplifier Explained
1 week ago A class-D amplifier is also known as a switching amplifier. Instead of boosting the input signal via linear gain stages, a class-D amplifier uses a concept known as pulse width modulation. This is a complicated subject, but this converts the input signal into pulses. The output stage then switches back and forth … See more

1 week ago The first Class-D amplifier was invented by British scientist Alec Reeves in the 1950s and was first called by that name in 1955. The first commercial product was a kit module called the X-10 released by Sinclair Radionics in 1964. However, it had an output power of only 2.5 watts. The Sinclair X-20 in 1966 produced 20 watts but suffered from the inconsistencies and limitations of the germanium-based bipolar junction transistors available at the time. As a result, these early class-D amplifier…
