I am using this site for reference : http://www.ecircuitcenter.com/Circuits/BJT_Diffamp1/BJT_Diffamp1.htm
and I just wanted to know the formula they used for differential gain, they got an answer of 20 V/V, is that mean the gain is 20dB of the circuit?
Also, I'm wondering what VCM, VS, VCC, VDD, VC1 and VC2 should be to get a gain of 20dB?
I am fairly new to this so some of these questions may seem stupid, but I really need help.
Cheers
