PCB design can limit the performance or reduce the reliability of a class-D amplifier if some basic layout guidelines are not followed. The following describes some good PC board layout practices for ...

PCB layout is very important to Class D amplifiers to obtain the best SNR, best thermal efficiency, and the lowest EMI. Any designer new to this field should examine proven designs to ascertain best ...

A class-D amplifier uses transistor switching ... Audio PCB design must be almost as careful as RF, although not for the crappy reasons audiophile tend to feed people.

Amplifier A is an amplifier rated as 160W/8ohm. The circuit boards have Upright Toroids, Resin-Potted Filter Caps, Connectors Everywhere and Bits of Copper Plane Everywhere. Amplifier B is an ...

Class D amplifiers always have an output filter to take out the high-frequency noise generated by the conversion process. The quality of this filter has a great bearing on the overall sonic ...

Amplifiers, which are fundamental elements of circuit design, take a small signal and make it larger. ... In a class D amplifier, power field-effect transistors (FETs) ...

Emitted EMI is a drawback to the switching topology of the Class D amplifier. ... Fortunately, other internal circuit design methods can be employed to mitigate electromagnetic interference (EMI).

Power supply decoupling, which is important in any Class D design if switching noise is not to degrade circuit operation, takes on a greater importance in the context of mixed signal chip design.
