介绍了一种超低静态电流无电阻电源复位电路。该电路用于能量收集系统中，将升压变换器从启动状态转换为PWM调制状态。它集成了电源复位（POR）和棕褐色检测（BOD）功能，没有电阻或带隙开销。在脉冲信号的产生中，采用双阈值检测（DTD）技术代替大尺寸延迟单元。电路以<inline-formula> < text -math符号="LaTeX">$0.13{\mu}\text{m}$ </ text -math></inline-formula>标准CMOS技术实现。电路的有效面积和静态电流分别为<inline-formula> < text -math notation="LaTeX">$154.4{\mu}\text{m}\,\，\乘以26.8{\mu}\text{m}$ </ text -math></inline-formula>，约为1nA。超低静态电流和小面积使所提出的电路适用于能量收集等低功耗应用。
An ultra-low quiescent current resistor-less power on reset circuit is presented in this brief. The circuit is used in energy harvesting systems to change boost converter from startup state to PWM modulation state. It integrates power on reset (POR) and brown out detection (BOD) functions without resistors or bandgaps overhead. Dual threshold detection (DTD) technology is used instead of a large size delay cell in generation of pulse signals. The circuit has been implemented in a <inline-formula> <tex-math notation="LaTeX">$0.13{\mu }\text{m}$ </tex-math></inline-formula> standard CMOS technology. The active area and the quiescent current of the circuit are <inline-formula> <tex-math notation="LaTeX">$154.4{\mu }\text{m}\,\,\times 26.8{\mu }\text{m}$ </tex-math></inline-formula> and about 1nA, respectively. Ultra-low quiescent current and small area make the proposed circuit suitable to be applied in low power applications like energy harvesting and beyond.
