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 ...

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 ...

Consumer demand for flexible audio features and hi-fi sound from mobile phones has led to handset audio chip designers having to optimise the Class D amplifier to meet the noise and power management ...

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 ...

The Class D amplifier topology theoretically offers ideal characteristics for audio: 100% efficiency, 0% THD, and no audible noise. While practical Class D implementations can come attractively close ...
