摘要：

<正>A third-order,sub-1 V bandgap voltage reference design for low-power supply,high-precision applications is presented.This design uses a current-mode compensation technique and temperature-dependent resistor ratio to obtain high-order curvature compensation.The circuit was designed and fabricated by SMIC 0.18μm CMOS technology.It produces an output reference of 713.6 mV.The temperature coefficient is 3.235 ppm/℃in the temperature range of-40 to 120℃,with a line regulation of 0.199 mV/V when the supply voltage varies from 0.95 to 3 V.The average current consumption of the whole circuit is 49μA at the supply voltage of 1 V.
