一种新型的电流模式曲率补偿带隙基准源
New Current-mode Curvature-compensated CMOS Bandgap
摘要
Abstract
A new sub-1V curvature-compensated CMOS bandgap reference (BGR) circuit is presented. Different from the conventional bandgap reference, a third current is introduced to eliminate the temperature nonlinearity of VEB of parasitic p-n-p bipolar junction transistor in CMOS process. The proposed circuit was designed and simulated in a standard 0. 18um CMOS process. The results show that the output reference voltage at 623 mV has a temperature coefficient of 4. 2 ppm/% from -55 % to +125 % , and a line regulation of 0. 9 mV/V at 1~2. 1 V is achieved.关键词
