摘要
本文提出了一种具有可编程电压阈值的多级POR电路，可以在不同的细粒度电源管理策略下工作。POR采用0.18 μ m标准逻辑CMOS技术设计，占地面积为110 μ m x 70 μ m。仿真结果表明，在19nA电流的情况下，该电路在工艺和温度变化(PVT)、上升时间范围为1µs到1s以及不同的电源值下都具有良好的性能。
An Ultra-Low Power Multi-Level Power-on Reset for Fine-Grained Power Management Strategies
This paper proposes a multi-level POR circuit with programmable voltage thresholds, that can operate in different fine-grained power management strategies. The POR is designed in a 0.18µm standard-logic CMOS technology, and occupies an area of 110µm x 70µm. Simulations results show a robust performance over process and temperature variations (PVT), rising times ranging from 1µs to 1s, and different supply values, while consuming a current of 19nA.
