Thanks for your explanation. So I should consider the two branch separately. With the same voltage change at the top, because Q2 area is larger than Q1 area, the I2 change will be larger than I1 change. That means the gain at point B is larger than point A. That's why point B should be the...
Hi guys,
Greetings from Juice!
I am new here and seeking for some help on the op-amp based bandgap reference.
I tried to analyze the polarity of the op-amp used in a bandgap reference.
My understanding is the function of op-amp is to force the voltages at the two input to be the same. So in...
