Low power timer 
Near/sub-threshold circuit design

Current Research:

- Ultra-low power gate-leakage based timer 
  For mm3-scale wireless sensor nodes, where only ~nW of power budget is available for year-long system lifetime, accurate synchronization cycle time measurement is required for low-energy radio communication. A multi-stage gate-leakage based timer reduces rms jitter by 8.1× and synchronization uncertainty by 4.1× with 660pW power consumption. With temperature compensation, effective temperature sensitivity is reduced to 31ppm/°C.

An 1.0mm3 general-purpose sensor node platform with heterogeneous multi-layer structure is developed to realize the 'smart dust vision' originally envisioned by Kris Pister. The node has low power I2C inter-layer communication and ultra-low power optical wakeup receiver. The system also includes two processors, power management unit with brown-out detection, timer, temperature sensor, and low-power imager. Standby power of the system was only ~10nW.
