Kopta, VladimirBarras, DavidEnz, Christian C.2017-01-242017-01-242017-01-24201610.1109/RFIC.2016.7508290https://infoscience.epfl.ch/handle/20.500.14299/133427WOS:000386517000054A low-power FM-UWB receiver intended for short range communications in wireless sensor networks is presented in this paper. It utilizes an "approximate zero IF" architecture which combines a free-running ring oscillator as the RF LO with a modified delay-line demodulator. The main benefit comes from implementing the gain stages and the demodulator at the IF instead of RF, allowing significant power savings. Integrated in a 65nm CMOS technology, the whole receiver chain consumes 420 mu W from a 1V supply while achieving -68dBm sensitivity at the data rate of 100 kb/s.FM-UWBwidebandlow powershort rangeapproximate zero IFuncertain IFHD-WSNtext::conference output::conference proceedings::conference paper
