Leakage-aware energy synchronization on twin-star nodes

To ensure sustainable operations of wireless sensor systems, environmental energy harvesting has been regarded as the right solution for long-term applications. In energy-dynamic environments, energy conservation is no longer considered necessarily ...

Battery-free sensor nodes rely solely on energy harvested from the environment and thus employ supercapacitors as energy storage to allow perpetual operation in absence of ambient energy. To guarantee that the sensor nodes can survive in periods where no ...

Dual-Vth technique is a mature and effective method for reducing leakage power consumption. Previously proposed algorithms assign logic gates with sufficient timing slack to high threshold voltage to reduce leakage power without impact on timing. ...
