Design of Low Power Wake-up Receiver for Wireless Sensor Network

Wireless Sensor Networks find various applications in different fields. Sensor nodes are small, low-cost and lowpowered communication devices. Hence designing a network with low power consumption is a critical issue in WSN. Different schemes are projected for achieving low power communication under short network range. To reduce the use of power and retaining a good lifetime, ultra-low power wakeup receiver is introduced. Energy dissipation is reduced here by maximizing data transceivers sleep time. In this paper, design and simulation of a wake-up receiver is carried out at 90nm and 45nm technology. Results are found to be satisfactory.
