| 摘要 |
A bandgap voltage reference circuit comprising a first circuit providing a first voltage substantially proportional to Vbc of a first bipolar transistor, a second circuit providing a second voltage DELTA Vbc substantially proportional to the difference of two Vbc voltages of two bipolar transistors, and a comparator having respective inputs coupled to Vbe and DELTA Vbe and an output coupled to the base of the first bipolar transistor whereby a voltage substantially proportional to the sum of respective constants multiplying Vbe and DELTA Vbe is provided at the output of the comparator. <IMAGE> |
