摘　　要：采用0.5um BiCMOS工艺设计了一种用于电源检测的上电复位电路。本文通过对比传统的上电复位电路,提出了一种结构新颖简单,性能可靠稳定的电路,最后利用Candence的Spectre给出了该电路在CSMC 0.5um工艺模型下的仿真后,结果表明,该电路的起拉电压相对稳定,受上电速率、温度和工艺的影响很小,性能远远优于传统的上电复位电路。A power - on - reset circuit for power supply detector is designed with 0.5um BiCMOS technology. The paper presented the PoR circuit of novel simple structure and high reliability compared with the traditional ones. The simulation was performed with 0.5um CSMC process model and Cadence Spectre, and the results show that the circuit has a stable and reliable performance, which is better than the traditional circuits. With the differences of supply voltage＇s ramp rate, temperature and process, the change of threshold voltage is in small distribution.
