Common emitter stage driving low hfe output stage
Say your output stage has a very high IQ for class A design (lets say 1 amp) but also has a low hfe of 80 (for example 2SC5200 STMicroelectronics | 497-10863-5-ND | DigiKey)
How do you go about driving this output stage without significant voltage drop (compared to an unloaded common emitter stage)?
The driver should have low output impedance and ability to source current. Another emitter follower is the popular solution. a CFP can provide some advantages.
