摘　　要：阐述一种具有电源上跳复位与低电压复位功能的上电复位电路。在Cadence仿真环境下,使用95纳米CMOS工艺对电路进行仿真验证。仿真结果显示,在5V的电源电压下,电路在标准工艺和温度条件下的上电复位阈值电压与低电平复位电压分别为1.62V与1.59V,并且在标准工艺条件下,上电复位阈值电压随温度变化的范围控制在2%以内。该电路能够适应不同的上电和下电时间,并且对于一定程度的电源电压瞬态波动,电路能够迅速产生复位信号。This paper describes a power-on reset circuit with both power-up reset and low-voltage reset capabilities.The circuit was simulated and verified in the Cadence simulation environment using a 95-nanometer CMOS process.The simulation results show that at a 5V power supply voltage,the power-on reset threshold voltage and the low-level reset voltage are 1.62V and 1.59V,respectively,under standard process and temperature conditions.Moreover,the power-on reset threshold voltage varies within a range of 2%with temperature changes under standard process conditions.This circuit is capable of accommodating different power-up and power-down times,and for a certain degree of power supply voltage transient fluctuations,the circuit can quickly generate a reset signal.
