Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

Transistors often find use as three-pin amplifier devices, in which the input and the output share one pin. Thus, the input and the output must have the same voltage at this pin. On the other hand, a ...

Editor's note: this is the final installment in this series. Part one is available at http://www.audiodesignline.com/howto/199202502 At 15 dB to 12 dB even very dense ...

Maxim claims two new Class D Speaker amplifiers provide Class AB audio performance with Class D efficiency for superior audio quality. Traditionally, electronics designers use analog amplifiers ...

The NCP2991 class AB audio amplifier from ON Semiconductor addresses two crucial requirements in today’s portable and wireless audio applications: noise-free audio amplification and fast response time ...

[Dino Segovis] wrote in to tell us about his “hack”, making an AB Audio Amplifier. The advantage of this particular amp is that the transistors never turn off, which would cause distortion. A full ...

ALEXANDRIA, Va.—William H. Doherty was an engineer with Bell Telephone Laboratories in 1936 when he invented a circuit that used two tubes running in Class B configuration to act as a linear amplifier ...
