Registration is required for external guests, and recommended SiCr employees. If you accept the event, it will pop-up in your calendar.

 

The Internet of Things (IoT) market requires radios that operate with very low average power consumption to enable battery life measured in years, or even battery-free operation.   Standards used in IoT applications, such as Bluetooth Low Energy, also have relaxed performance requirements allowing the radio to be optimized for low power operation.   This tutorial will introduce several types oscillators used in these IoT radios, explaining how the low power system level requirements influence the oscillator architecture, design, and performance targets.   Design examples and power/accuracy tradeoffs will be described for sleep timers, RF synthesizer reference clocks and high frequency VCOs, and system clocks used for the MCU and peripherals.   At the end of the tutorial, attendees will have a solid overview of the many types of oscillators present in a typical IoT wireless node and understand design tradeoffs for each.

 

Danielle Griffith received the B.S.E.E. and M.Eng. degrees from the Massachusetts Institute of Technology, Cambridge in 1996 and 1997, respectively. She joined Motorola in Tempe, AZ in 1997 and worked in the area of RF circuit design.  In 2003, she joined Texas Instruments in Dallas, Texas and is a Fellow in the Connectivity business unit.  She develops circuits and techniques for reducing cost, power consumption, and circuit board area for low power wireless connectivity products.  Her current focus areas are architectures for efficient wireless systems, low power oscillators and MEMS circuitry.  She has published >50 papers, most of them in IEEE journals or conferences.   She has written a book chapter titled “Synchronization Clocks for Ultra-Low Power Wireless Networks” which was published by Springer as a part of the book “Ultra-Low-Power Short-Range Radios”.  Danielle holds 19 issued US patents and has given multiple university and IEEE conference tutorial and workshop sessions.  She was a member of the Technical Program Committees for the IEEE RFIC Symposium for conferences years 2014 and 2015, the IEEE International Solid-State Circuits Conference for conference years 2015-2019, and the VLSI Symposium starting in 2019.
