中文摘要：
介绍了一个带曲率补偿的低电压带隙基准源．由于采用电流模结构，带隙基准源的最低电源电压为900mV．通过VEB线性化补偿技术，带隙基准源在0到150℃的温度范围内的温度系数为10ppm／℃．在电源电压为1．1V时，电源电流为43μA，低频的PSRR为55dB．该带隙基准源已通过UMC0．18μm混合信号工艺验证，芯片面积为0．186mm^2．
英文摘要：
A low voltage bandgap reference with curvature compensation is presented. Using current mode structure, the proposed bandgap circuit has a minimum voltage of 900mV. Compensated through the VEB linearization technique, this bandgap reference can reach a temperature coefficient of 10ppmFC from 0 to 150℃. With a 1.1V supply voltage,the supply current is 43μA and the PSRR is 55dB at DC frequency. This bandgap reference has been verified in a UMC 0.18μm mixed mode CMOS technology and occupies 0. 186mm^2 of chip area.
