hi 40,i'm using the 2n2222 to design a class A amplifier .I want to calculate my power gain wich depends on beta value ,i set the current at Ic=200ma and Vce=4v what should i do?
You should design a voltage amplifier with lower current then follow it with a power amplifier to handle the higher current.what should i do?
The usual way to do this is to design a circuit that really doesn't depend very much on the beta of the transistor. Do you have a schematic of what your idea is? We can work with that pretty well.crutschow the power gain depends on beta value how to stabilize that??ap gain is equal to (Ap=beta*Rc*ic0/Vt)
