Abstract— Many of the complex VLSI systems have separate I/O and core supplies and follow a predefined power up sequence. In this paper an on-chip power-on reset (POR) strategy and an I/O power supply detection circuit with low steady-state power consumption are proposed. Our technique allows the I/O power supply monitoring, independently from the core power supplies. The I/O power supply detection circuit can detect both ramp up and ramp dowvn of the supply oltage and has a fixed detection threshold. The circuit can operate for any I/O supply voltage level ranging from 1.5V to 3.3V. Simulation results show a maximum steady state power consumption of 23μW. Due to this fact the proposed POR circuit is suitable for low power applications and embedding in portable device systems.

摘要:超大规模集成电路系统有许多复杂单独的I / O与核心供应，并按照预定顺序提供电源。在本文中推荐了复位片上电源（POR）和一个I / O电源低稳态功率检测电路耗能的方法。我们的技术允许I / O电源的电源监控，独立于内核的电源供应。该I / O电源检测电路可以检测两个斜坡上升和下降的电源电压和拥有一个固定的检测阈值。该电路可以支持任何I/ O电源电压水平范围从1.5V到3.3V。模拟结果显示，最大稳态23μW功耗。由于这一点可知POR电路为低电源应用，可适合于嵌入在便携式设备系统。
