(This is not homework)
Okay I'm writing a lab report and just writing some discussion. Also I am curious myself.
I'm a junior in computer engineering.
I want to discuss the differences between BJT and MOSFETs as amplifiers and anything like pros/cons for each.
Also why is the BJT gain so much higher than the MOSFET gain? Feel free to use formulas, small signal model, to explain and justify.
In the lab specifically we did Common-Source, Drain, and Common-collector,emitter amplifiers.
Of course for the C-D and C-C amplififiers my small signal voltage gain Av was about .9 for both or around unity gain.
But for the other 2, the difference was -20 and 72. WHY is there this difference?
