Wireless sensor networks (WSNs) have become highly sought after in myriad of applications, including health care, environmental monitoring, industrial settings, and agriculture. The nature of these applications imposes severe restrictions on the power consumption of a WSN node. As a result, power-efficient communication schemes and ultralow-power (ULP) radio frequency (RF) front-end circuits are required to maximize battery lifetime and to enable operation using energy harvested from the environment.
