Abstract :
This paper presents the first monolithically integrated RF-power harvesting 71 GHz wireless temperature sensor node in 65nm CMOS technology, containing a monopole antenna, a 71 GHz RF power harvesting unit with storage capacitor array, an End-of-Burst monitor, a temperature sensor and an ultra-low-power transmitter at 79 GHz. At 71 GHz, the RF to DC converter achieves a power conversion efficiency of 8% for 5 dBm input power.
