3 年前· 来自专栏 模拟IC设计实践 mikar me/ee关注本文介绍一个通用的POR电路(李发宁王炜马侠, patentguru.com/cn/searc),设计时要特别注意M1和M2的滞回区选取,保证VDD上电到足够高的电平时输出才置位,下电到足够低时输出才复位。 图1 POR电路原理图 工作原理: 图1为一个简单的低功耗POR 电路示意图。
The purpose of the invention is that a power-on reset circuit can stably function even if being shared by a voltage source and a voltage of an IC. The power-on reset circuit (100A) includes a first resistor (R1) having one end (R1-L) connected to a power source node (N1); a ...
