ABSTRACT
Internet of Things (IoT) devices were projected to be installed in every object surrounding us. Most of the IoT sensing and communication circuits only operate for a very short amount of time and sleep or stand by for a much longer time, as shown in Figure 2.1. This very low-duty-cycle and high peak-to-average power ratio operation feature makes the ultralow standby power a critical specification for the IoT devices to prolong the battery life and recharging cycle.
