摘要

This paper presents the design of an innovative discrete-time (DT) wake-up receiver (WuRx) for short-range wireless sensor networks. A switched-capacitor architecture was adopted to implement a digital filter providing some adjustment of the receiver parameters. The inherent aliasing susceptibility of the digital filter is opposed by the current sampler structure as it performs an anti-aliasing fu...
