Design and modeling of heterogeneous semi-active wake-up radio for sensor network applications

This paper compares the performances of an 868MHz semi-active wake-up radio using two different integration approaches: a heterogeneous fabrication, combining PCB and integrated CMOS; and a more classical PCB integration. The critical and most consuming part of the device is designed on purpose by using a CMOS integrated technology, based on the g

methodology, to improve the sensitivity and reduce the overall consumption of the device. SPICE results are provided, including worst case and Monte-Carlo simulations, then the subsequent characteristics are implemented in OMNeT++. Finally, wireless sensor network communications are simulated to evaluate the influence of the design on high-level performances of the nodes.
