darlington amplifier

Hi all, i know a darlington amplifier gives high current gain, so my question is, does this means it will give high power gain as well cause P=VI?

if yes, will the power gain be extremely large ?(i read some books say the current gain can go up to 10000.)

thanks for the reply.

Yes, you can get a lot of power gain. Keep in mind, though, that MOSFETs and JFETs have essentially zero gate current, so they can also achieve enormous power gain.

Darlington Pairs have another undesirable characteristic, they have a Collector Emitter drop of .6 to .7V. This can add to some serious wattage with large currents, and their Base Emitter drop is 1.2-1.4V.

Sziklai Pairs do the same thing as Darlington's, but only drop .6-.7V Base Emitter. Other than that they are pretty similar to a Darlington, including the .6-.7 Collector Emitter drop at saturation.
