A 130µA Wake-Up Receiver SoC in 0.13µm CMOS for Reducing Standby Power of An Electric Appliance Controlled by An Infrared Remote Controller

📋 论文概要

该论文提出了一款采用0.13μm CMOS工艺的130µA唤醒接收器SoC，用于降低由红外遥控器控制的家电待机功耗。解决了传统红外遥控器无法实现唤醒功能的问题，通过集成唤醒电路显著减少了AC-DC转换器造成的待机功率损失。

💡 主要创新点

• 首次将唤醒电路与红外遥控接收器集成在单个SoC中，实现低待机功耗的遥控方案。
• 实现了超低功耗（130µA）的唤醒接收器，适用于电池或能量采集供电的应用场景。
• 采用0.13μm CMOS工艺，在低功耗与低成本之间取得良好平衡。

zero emissions of carbon dioxide, wake-up circuits have attracted attention as a promising approach for reducing standby power [1]. The dominant consumers of standby power are household electric appliances driven by AC power such as TVs. In these appliances, power is lost at an AC-DC converter even when the appliances are turned off. Although an infrared remote controller (IRC) is usually used in these appliances, an RF signal is utilized in the wake-up circuits reported so far and no wake-up circuit has been reported for the IRC. This paper describes a receiver (RX) SoC with wakeup function for the IRC. Figure 12.6.1 shows the concept of the proposed low-standby-power IRC system. In a conventional system, the main AC-DC converter is turned off when an
