摘　　要：设计了一种新型低功耗上电复位电路。该电路采用一种低功耗施密特触发器,整体电路静态工作电流极低,复位脉冲出现时间和脉冲宽度可调。电路基于40nm CMOS工艺,在1.1V电源电压下进行Cadence仿真。结果表明,新型上电复位电路静态电流为63nA,在电源缓慢上电、高电源纹波和快速掉电/上电等情况下,电路均具有很高的可靠性。A novel low dissipation power-on reset circuit was designed,in which a low power dissipation Schmitt trigger was used.The circuit had an extremely low quiescent operating current,and adjustable reset pulse appearing time and pulse width.Based on 40 nm CMOS process,the circuit was simulated with Cadence at 1.1 V supply voltage.Simulation results showed that the novel power-on reset circuit had a quiescent current of 63 nA,and it operated stably and reliably in long power-on time,high power supply ripple and fast power-off/power-on.
