[Part 1 of this article provides an overview of Class D amplifiers, and offers answers on amplifier selection and Class D amplifier filter design.] What is a Zobel? A Zobel is an impedance matching ...

A block diagram of the Class-D amplifier is shown in Figure 1. The techniques discussed in this paper describe how a single-frequency, sine wave signal was generated through a Class-D amplifier with ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

Sincea Class D amplifier has an output that switches between on and off, thenoise created by that switching must be filtered out. "You just have tobe careful with the filter design and circuit ...

The DDFA architecture employs a fast and highly accurate digital feedback loop to create a Class-D audio switching amplifier that sets new standards in digital amplifier sound quality.
