A high or low temperature compensation bandgap reference voltage with pre-regulated voltage circuit
分析了带隙基准电压分段补偿技术与基本原理, 提出一种具有预稳压功能的高低温补偿带隙基准电路。应用高低温补偿电路优化了温度系数, 设置预稳压电路提高了带隙基准电路的电源抑制比。基于0.35 μm标准CMOS工艺设计并绘制了电路及版图。仿真结果表明, 在-55~125℃范围内, 温漂系数仅为1.8×10-6/℃; 电源抑制比为-84.6 dB(在1 kHz下); 在2.6~5 V的电源幅度范围下, 电源抑制性能为19.6 μV/V。该电路可应用于高精度系统设计中。...
