Thanks for your help djhuber, I do think its something like that, but anything more specific or quantitative would be great. From what I can figure out the biasing on the CB amplifier reduces Ic, reducing gm and the gain. Similarly, the same refrence current is used for the darlington pair, and...
As far as I know it assumes ideal power supplies for Vcc and Vee. Vcc is exactly +x volts and Vee is exactly -x volts, where both can provide any amount of current needed.
I don't know if its important, but the CB amplifier right after the input stage is biased (at the base) by a transistor...
Hello,
I was wondering if anyone could explain why the open-loop gain of the 741 is so dependant on the supply voltage. The spec sheet I have show it dropping by about 20dB between Vcc = 2V and 18V.
As I understand it, the gain in the 741 comes from the Common Base stage after the input...
