Abstract or Summary
  • A fully integrated CMOS latched comparator is presented for use as a wake-up circuit that is attached to an RF energy harvester in a battery free wireless sensor network. The system consumes less than 36nA static current at 20°C and dissipates 2pJ of energy per conversion. The comparator comprises of a series of level-shifting leakage-mode inverters. Its latching behavior is obtained by supplying the power to each stage from the inverted output of the last stage via a resistor-string voltage divider. This 45nW circuit is the solution with the lowest static power consumption proposed to date for synchronizing nodes in a sensor network.
