Abstract

This paper presents a resistorless bandgap reference with minimized quiescent current, designed in a CMOS 0.35um/5V technology. The circuit relies on strong inversion operation, and the “inverse function”, achieving first order temperature compensation. Simulation results indicate 20ppm/deg.C between -40deg.C to 125deg.C, 6uA quiescent current and 2.8V minimum supply voltage.

具有最小电流消耗的CMOS无电阻带隙基准
本文提出了一种采用CMOS 0.35um/5V工艺设计的静态电流最小的无阻带隙基准电路。该电路依靠强反转运算和“逆函数”,实现一阶温度补偿。仿真结果表明,在-40°c至125°c之间,20ppm/℃,6uA静态电流和2.8V最小电源电压。
