So i need to build a high gain diff amp. Only BJT,s available.
need +- 7.5 Volt swing
Typically i can't get a but diff amp to give me a gain of more then a 100 or so. I need 800 differential gain
So the first thought is to cascade a few together. However, as the output voltage goes up and goes into the base of the next stage all i get is clipping.
Say i built a single stage diff amp and then wanted to just get a bunch of gain out of it. Take the output and maybe run it into a Common emitter maybe
How do i get the common emitter to not clip with a large input signal?
Any other thoughts or proposed ideas on how to do this?
