Zhao, Y. (author), Dong, Y. (author), Gerrits, J.F.M. (author), Van Veenendaal, G. (author), Ling, J.R. (author), Farserotu, J.R. (author)A 9 mW FM-UWB receiver front-end for low data rate (<50 kbps), short range (<10 m) applications operating in the ultra-wideband (UWB) band centered at 7.45 GHz is described in this paper. A single-ended-to-differential preamplifier with 30 dB voltage gain, a 1 GHz bandwidth FM demodulator, and a combined (preamp/demodulator) receiver front-end...journal article 2009

Gerrits, J.F.M. (author), Kouwenhoven, M.H.L. (author), Van Der Meer, P.R. (author), Farserotu, J.R. (author), Long, J.R. (author)This paper presents a novel UWB communications system using double FM: a low-modulation index digital FSK followed by a high-modulation index analog FM to create a constant-envelope UWB signal. FDMA techniques at the subcarrier level are exploited to accommodate multiple users. The system is intended for low (110 kbps) and medium (1001000 kbps)...journal article 2005
