Low-power high-precision timing hardware for sensor networks

In this demonstration, we will present three key technologies we recently developed to improve time synchronization accuracy in sensor networks: (1) Temperature Driven Time Synchronization, (2) Low-Power Sub-μSecond Time Synchronization, and (3) Low-Power FPGA implementation of a High-Low Timer.
