Towards zero: Power consumption trends in low data rate wireless connectivity products

The low power IoT market began in earnest in 1999 with the launch of the first commercial Bluetooth® device.  Analysis of >200 datasheets and published IEEE conference and journal papers shows that since then, active power consumption for these low data rate radios has reduced by 20x, while sensitivity has improved by 15dB.  Large power reductions have also been seen in metrics such as the standby and BLE-1s connection interval currents.  This talk will explore which innovations have made this possible, and what power consumption trends we can we expect in the future.   Questions to be addressed include:  How does power consumption trade off with data rate, transmit power and receiver sensitivity? How low power is low enough? Where do wakeup radios and energy harvesting fit into this?  Where will it all end?


Danielle Griffith received the B.S.E.E. and M.Eng. degrees from the Massachusetts Institute of Technology, Cambridge.   In 2003, she joined Texas Instruments in Dallas, Texas and is a Fellow in the Connectivity business unit.  Her current focus areas are circuits and architectures for efficient wireless systems, low power oscillators and MEMS circuitry.   She has published a book chapter and >50 papers, most of them in IEEE journals or conferences.   Danielle holds 19 issued US patents and has given numerous university and IEEE conference tutorial and workshop sessions.  She has been a member of the Technical Program Committees for the IEEE RFIC Symposium (2014-2015), IEEE International Solid-State Circuits Conference (2016-2019), and the IEEE VLSI Symposium (2019-2020).  She is a senior member of the IEEE, an associate editor of the IEEE Journal of Solid-State Circuits since 2020, and has been selected as Distinguished Lecturer of the IEEE Solid-State Circuits Society for 2021–2022.
