A high or low temperature compensation bandgap reference voltage with pre-regulated voltage circuit
Xibei Gongye Daxue Xuebao, 2022 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。

Advanced Functional Materials, EarlyView.Eu‐doped {ZnCdO/ZnO} structures grown on Si are developed, showcasing dual‐functionality controlled by europium doping. While high europium concentration transforms the device into an ultrafast, self‐powered photodetector, low‐doped structures can be used as an optoelectronic synapse.

Advanced Functional Materials, EarlyView.A post‐growth method is demonstrated to realize energy‐tunable quantum emitters in GaAs/GaAsN/GaAs core–multishell nanowires on a Si substrate. By combining the N‐induced bandgap reduction with H‐ion irradiation, the GaAsN potential landscape is engineered, enabling isolated, narrow emission lines that function as single‐photon sources with g(2)(0) ∼ 0.

Advanced Functional Materials, EarlyView.We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Advanced Functional Materials, EarlyView.A self‐healable polymer matrix, crosslinked via dynamic imine bonds, is synergistically coupled with a LiPF6–LiDFOB dual‐salt system to decouple Li+ from the polymer matrix, enabling fast Li+ transport. This strategy offers an effective pathway toward high‐performance, next‐generation gel‐polymer‐based Li‐metal batteries.
