Abstract

A low-power capacitorless demultiplexer-based multi-voltage domain low-dropout regulator (MVD-LDO) with 180 nm CMOS technology is proposed in this work. The MVD-LDO has a 1.5 V supply voltage headroom and regulates an output from four voltage domains ranging from 0.8 V to 1.4 V, with a high current efficiency of 99.98% with quiescent current of 53 µA with the aid of an integrated low-power demultiplexer controller which consumes only 68.85 pW. The fabricated chip has an area of 0.149 mm and can deliver up to 400 mA of current. The MVD-LDO's line and load regulations are 1.85 mV/V and 0.0003 mV/mA for the low-output voltage domain and 3.53 mV/V and 0.079 mV/mA for the high-output voltage domain. The LDO consumes only 174.5 µW in standby mode, making it suitable for integrating with an RF energy harvester chip to power sensor nodes.

摘要

本文提出了一种采用180纳米CMOS技术、基于低功耗无电容解复用器的多电压域低压差稳压器（MVD-LDO）。该MVD-LDO具有1.5V的电源电压裕量，可调节来自四个电压域的输出，电压范围为0.8V至1.4V，借助仅消耗68.85 pW的集成低功耗解复用器控制器，静态电流为53μA时，电流效率高达99.98%。所制造芯片的面积为0.149平方毫米，可提供高达400mA的电流。对于低输出电压域，MVD-LDO的线性调节和负载调节分别为1.85mV/V和0.0003mV/mA；对于高输出电压域，分别为3.53mV/V和0.079mV/mA。该LDO在待机模式下仅消耗174.5μW，适用于与射频能量采集芯片集成，为传感器节点供电。
