Is it darlington pair??Assume A is a standard operational amplifier with e.g. 20 mA maximum output current and compensation current Is is is as high as 200 mA. Then you need a current booster stage like the complementary emitter follower shown in the schematic.
It is not a darlington amplifier it is a Class B power amplifierIs it darlington pair??
how this working here?
power amplifier n emitter follower pair
