This presentation shows radio frequency (RF) design solutions for wireless sensor nodes to address sustainability issues in the Internet of Things (IoT), which arise due to the massive deployment of wireless IoT nodes on environmental and economic levels. Engineers can apply these RF design solutions to improve the ultra-low-power operation of IoT nodes, avoid batteries’ eco-toxicity, and decrease maintenance costs due to battery replacement. The solutions offer high integration levels based on system-on-chip and system-in-package concepts in low-cost complementary metal-oxide-semiconductor technologies to limit these nodes’ costs and footprints. In particular, the presentation covers solutions for ultra-low-power wireless communication systems based on high-frequency (HF) and ultra-high frequency (UHF) radio frequency identification (RFID) technologies. The talk offers RF design solutions for HF and UHF RFID systems, revealing how to develop passive miniaturized IoT nodes that operate robustly in harsh application environments.
