Summary:
This paper provides a noise coupling effect on reference voltage level of triggering circuit which determines a digital signal from an analog signal in non-coherent Ultra Wide-Band (UWB) communication system. A coupled noise to reference voltage level brings a large timing variation in a reconstructed digital signal. This coupled noise can be expressed as a combination of multiple frequencies and phases. This paper shows two worst noise waveforms with highest-positive peak and lowest-negative peak. Also, it predicts the worst timing variation in the reconstructed digital signal.
