If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier that ...

Audiophiles spend a lot of time and effort worrying about audio specs like Total Harmonic Distortion (THD). Makes sense, because THD affects the quality of audio reproduction. However, THD can also ...

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 ...

The circuit is all about a power amplifier that can provide a power output of 60 W while operating in Class A mode. Class A – refers to an output stage where the bias current is greater than the ...

The essentials of current-mode-control modeling. What are modified average models? Verifying new LTspice models for different, previously unsupported power-supply topologies. When a power-supply ...

Determine the voltage gain and the power gain of the Class-A power amplifier shown in the Figure. Assume for all transistors. Notice that the first stage is a voltage-divider biased common emitter ...
