For driving an antenna, efficient generation of a clean and stable signal is required for optimum performance of many systems. This paper focuses on methodologies to efficiently apply a pure, ...

International Rectifier's IRAUDAMP1 Class-D audio-amplifier reference design gives engineers a preconfigured circuit that delivers 500W of peak power in each of two stereo channels into 4Ω ...

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. Fig 2. The blue line shows the energy ...

Embedded electronics has continued to ramp up across the automotive landscape, taking on more substantial roles in many applications. One example is the presence of multiple class-D audio amplifiers ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.
