A self-duty-cycled and synchronized UWB receiver SoC consuming 375pJ/b for −76.5dBm sensitivity at 2Mb/s

Novel highly networked applications with severe energy constraints such as tag and body-area networks, for ubiquitous object networking or the `Internet of Things' are driving the need for ultra-low-power wireless data links that operate over a short range and with a relatively low data rate. Impulse radio UWB (IR-UWB) has shown unique promise for these applications; however, the synchronization and bit-level duty cycling of the receiver have remained a significant challenge. In this work, we present a fully bit-level-duty-cycled IR-UWB receiver SoC with a clock-and-data-recovery(CDR)-based synchronization for demodulation and self-duty cycling. The SoC contains the full receiver from RF signal in to clocked digital data bits out.
