In my simple bandgap design , I simulation the slope of Vbe and delta Vbe in TSMC
technology. But the slope of delta Vbe is not k/q(lnn), much smaller. so I have to increase the ratio of R1/R0. So the Vref is not 1.25V , almost 2V
What is wrong? I sim the circuit in chartered technology ,It is the same.
