Transistor small signal analysis
Hello all,
I would want to study a low noise preamp with small signal analysis, but I don't really know I can do.
I would want to calculate the gain of the amplifier.
I tried to deduce the equivalent schematic in small signal analysis, but I don't know how I can start with this two stage, do I separate them ? and how ? What is the method to do the analysis with multiple stages like this ?
Another question, how can I deduce the 1/y11 and 1/y22 values ?
I hope that you coudl help me
Thanks
