Session 28 overview: Wireless connectivity: Wireless subcommittee

Connecting things wirelessly requires optimization from multidisciplinary areas. This session will introduce state-of-the-art wireless transceivers supporting ultra-lower-power IoT and connectivity solutions. In this session, a high-performance WLAN SoC supporting up to 802.11ax 1024QAM will be presented. Then, two-blockers-tolerant high-sensitivity Bluetooth Low-Energy (BLE) transceivers in 65nm and 40nm CMOS will be presented followed by a best-in-class performance all-digital PLL for BLE in 16nm FinFET technology, and an energy-harvesting BLE transmitter in 28nm CMOS. An ultra-low-power wakeup receiver enabling event-driven sensor nodes and an ultrasonic wake-up receiver using a precharged capacitive micro-machined ultrasound transducer will be shown. Finally, a 5.8GHz near-field radio achieving the smallest die size of 116μm×116μm will be presented in this session.
