A 130μA wake-up receiver SoC in 0.13μm CMOS for reducing standby power of an electric appliance controlled by an infrared remote controller

In the context of efforts to achieve zero emissions of carbon dioxide, wake-up circuits have attracted attention as a promising approach for reducing standby power. 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 wake up function for the IRC.
