Dissipation consists mainly of resistive losses, (Output Current) 2 * R. Figure 3 illustrates the efficiency of the sinewave input and also shows the distortion of the output signal. That distortion ...

Class AB amplifiers have been around for a long time, and even with Class D designs becoming more common, there’s stil ...

IRVINE, CA. Pasternack has just launched a new series of high-power, class AB broadband amplifier modules that incorporate GaN, LDMOS, or VDMOS semiconductor technology. The combination of high ...

[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 ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...
