Hi guys,
I am new here. Currently I am working on a school project that requires me to build an "amplifier". Will be using only DC voltage for it's operation.
So far I am using an emitter bias to have negative feedback. My problem is how am I going to know how much voltage I require across the emitter resistor so that I will get a constant 10mA collector current. With that in mind the larger the signal swing the better.
I did some research and some books suggested to use 1/3 of Vcc while others suggested using 1/10 of Vcc, but how much is enough?
