|Amplifier Teaching Aid (DED Philippinen, 86 p.)|
|Lesson 10 - Large Signal Amplifier|
The amplifiers we have discussed have been class A amplifiers. Class A amplifier operate in the center of the load line. This gives the best possible output swing without clipping.
Efficiency: low, maximum 50%
Even when no signal is applied, a high current is flowing (100 mA) and there is a power dissipation in the load.
Applications: Few audio amplifier (high quality)
