Transistors often find use as three-pin amplifier devices, in which the input and the output share one pin. Thus, the input and the output must have the same voltage at this pin. On the other hand, a ...

Bias circuits for class AB buffers don't have to ruin your total harmonic distortion spec. ... it is omitted in a practical circuit and diodes D1-D4 can be substituted with one red LED.

A 1 kΩ collector resistor and a 330 kΩ base resistor has never failed me for a small-signal self-biasing audio amplifier, I’m nothing if not a creature of habit.

In this example of a pulsed amplifier design, the signal source has been biased by a 1-GO resistance to ground, and the JFET source is biased using a fast diode, a 1N4148, at a source-drain ...

The amp is rated at 50W per channel in high-biased Class A/AB mode, delivering most of its power in Class A state. All of which is a roundabout way of saying it has the power to drive a wide range ...
