A low complexity digital frequency calibration with high jitter immunity for ultra-low-power oscillators
Autor: M. Scholl, R. Wunderlich, S. Heinen
Publikováno v: Advances in Radio Science, Vol 17, Pp 145-150 (2019)
This paper presents a highly efficient digital frequency calibration method for ultra-low-power oscillators in wireless communication systems. This calibration method locks the ultra-low-power oscillator's output frequency to the reference clock of t

Analysis of the frequency conversion of spurious tones in frequency dividers and development of an event-driven model for system simulations
Autor: C. Beyerstedt, J. Meier, F. Speicher, R. Wunderlich, S. Heinen
Publikováno v: Advances in Radio Science, Vol 17, Pp 101-107 (2019)
This paper presents a frequency domain analysis of spurious tones in frequency dividers. The results of the analysis are used to develop an event-driven model for system simulations which work entirely in the frequency domain. The proposed approach i

A digital receiver signal strength detector for multi-standard low-IF receivers
Autor: T. Saalfeld, T. Piwczyk, R. Wunderlich, S. Heinen
Publikováno v: Advances in Radio Science, Vol 16, Pp 51-57 (2018)
This paper presents a receiver signal strength detector based on a discrete Fourier transform implementation. The energy detection algorithm has been designed and measured using a custom multi-standard transceiver ASIC with a low-IF receiver at 0.

Implementation of envelope detection based Wake-Up Receiver for IEEE 802.15.4 WPAN from off-the-shelf components
Autor: J. Arndt, L. Krystofiak, V. Bonehi, R. Wunderlich, S. Heinen
Publikováno v: Advances in Radio Science, Vol 15, Pp 107-113 (2017)
Power consumption in wireless networks is crucial. In most scenarios the transmission time is short compared to the idle listening time for data transmission, the most power is consumed by the receiver. In low latency systems there is a need for l
