Design and Implementation Wake-up Module for Wireless Sensor Node using Dynamic Reference Voltage Demodulation Circuit

동적 기준전압 복조회로를 이용한 WBAN/USN 센서노드용 웨이크 업 모듈의 설계 및 구현

This paper designs and implements wake up module for WBAN/USN sensor node which is using dynamic reference voltage demodulation circuit. When a comparator is used in a system for detecting received voltage level, comparator must have a reference voltage. However, the reference voltage is fixed, the system can communicate only a few range because received voltage level is changing widely due to distance of the wireless sensor nodes. Therefore, the proposed wake up module employs a dynamic reference voltage demodulation circuit for increasing communication range.
