摘　　要：提出了一种新型的低压低功耗上电复位电路。该电路利用MOS管多种二级效应,采用多种低压低功耗技术,满足降低功耗的需要。整个上电复位电路的静态功耗低于1μW,应用于1.8 V与1.2 V电源电压。设计采用SMIC 0.18μm EEPROM工艺,可应用于其他低电源电压以及低功耗要求的芯片设计。A new power-on-reset circuit with low voltage and low power was presented, which made use of second-order effects of MOS transistors. A number of technologies were adopted to achieve low voltage and low power. The circuit functions well at 1.8 V or 1.2 V supply voltage with static power less than 1 tlW. The design was implemented in SMIC＇s 0. 18μm EEPROM technology. And it could be used for applications where low voltage and low power are required.
