Hi,
I have a question to the simple common emitter amplifier with current source load as in the picture. I thought the voltage gain should be in this case "A=gm/go" which is around 2100, but its only 330. For small currents this formula seems to be correct, but it's getting more worse the higher the current. Can somebody explain me please the reason for this effect?
Thanks
