     The most commonly used bandgap reference is carried out by the sum of V_BE and kV_T,for the built-in characteristics of active devices, the reference voltage always right around 1.25 V. The low voltage reference is realized by the sum of two currents which are proportional to V_BE and kV_T respectively.
     普通的带隙基准是通过VBE(双极型晶体管的基极-发射极电压)和kVT(VT=k·T/q)的和来实现输出基准电平,由于器件本身的特性而决定了其输出电平一般在1.25V左右。 本文的带隙基准通过两个分别正比于VBE和kVT和的电流的叠加来实现低电平输出。
