hello,
I am trying to design a multistage amplifier using a darlington pair transistor. My total gain that I am trying to amplify is 160. My load is 40ohm and the input resistance is 120kohm.
The darlington pair is triggered by a very low current, which is why I want to use it in the first stage, because of the high input resistance. The darlington pair has a gain of 1. So if I want to only use 2 total stages, the next stage would have to have an amplifier with a gain of 160. Which amplifier should i use in this situation? (common emitter, common source, with full bypass, partial, or no bypass)
Thanks
