An ultra-low power wake-up receiver for 2.4-GHz wireless sensor networks, based on a fast sampling method, is presented. A novel multi-branch receiver architecture covers a wide range of interferer scenarios for highly occupied radio channels. The scalability of current consumption versus data rate at a constant sensitivity is another useful feature that(More)
This paper introduces a novel approach for ultra-low-power radio receivers based on Armstrong's super-regenerative architecture. With a power consumption of 1 μW or less the receiver presents a big improvement to the state-of-the-art of 400 μW. In consequence, low maintenance wireless networks are much more feasible. Receiver sensitivity is(More)
This paper describes an innovative approach for integrated ultra-low current wireless receivers for UHF bands in a 180-nm CMOS technology. The classical method of slow periodic switching off of the receiver was picked up, essentially enhanced and applied to a superheterodyne receiver topology. A novel fast sampling pulse operation method for ultra low power(More)
Localization and asset tracking are key components of the Internet of Things or the fourth industrial revolution called “Industry 4.0”. Current systems using GPS signals cannot be used indoors. Alternative systems for indoor localization exist, but they cannot be battery power with tiny batteries over multiple years. To overcome these(More)
