Paper Abstract

A critical issue of Wireless Sensor Networks circuits is energy management. This work presents a Radio-Triggered Wake-Up solution designed and developed for WSN based systems. The proposed circuit manages, in a simple and efficient way, node switching between sleep mode and both receiving or transmitting active modes. It uses a HW hearing circuit, which lowers power consumption and avoids extra processing on the main microcontroller. The weak-up is selective with predefined recognition patterns without the microcontroller intervention. Furthermore, it is tiny in size, and the whole circuit is suitable for single CMOS chip integration. The circuit has been tested to demonstrate the Wake- Up proposal worthiness. With only 8.7 microwatts of power consumption (@ 3.0 Vdc) the system successfully Wake-Up nodes up to 15 meters away from the transmission source. This performance improves solutions presented in previous research works.
