摘要/Abstract：

We propose a bandgap reference, which works in sub-threshold regions to the reduce power consumptionin applications such as those in energy harvesting systems that stimulate the development of power management forlow power consumption applications. Measurements shows that the supply current of the proposed bandgap referenceis only 6.87 μA, including a voltage buffer consuming 3.6 μA of supply current, when the supply voltage is 5 V. Thesupply voltage can vary from 3 to 11 V and the line regulation of the proposed bandgap reference output voltage is0.875 mV/V at room temperature. The temperature coefficiency is 88.9 ppm from 10 to 100 ° C when the supplyvoltage is 5 V.
