Abstract

This paper describes a wireless-powered UWB system-on-a-chip (SoC) tag for area-constrained localization applications. An antenna-rectifier co-design methodology optimizes sensitivity under area constraints. A 300-nA power management unit (PMU) and low-voltage (0.8-V) UWB TX reduces tag load and required rectifier output voltage. The rectifer, PMU and UWB TX are integrated in 65nm CMOS and the rectifier demonstrates state-of-the-art -30.7 dBm sensitivity for 1 V output voltage with only 1.3 cm2 antenna area. Wireless measurements demonstrate sub-10 cm range resolution at range exceeding 10 m.
