A 6-8GHZ 200MHz Bandwidth 9-Channel VWB Transceiver with 8 Frequency-Hopping Subbands

This paper presents a pulse-based OOK transceiver system which enables up to 9-channel transmission over 6-8GHz frequency band for the first time. Having eight frequency-hopping subbands, a very-wideband (VWB) transceiver achieves a 200MHz bandwidth with steep spectral roll-off and complies with ultra-wideband (UWB) emission mask. The VWB transmission with l-64ns pulse duration offers a flexible communication range and a relaxed pulse generation circuit design in the transmitter. In the receiver, an asynchronous energy detection (AED) method which does not require multiphase clock generation is employed. The proposed VWB transceiver implemented in 65nm CMOS consumes 0.81 mW with 20ns pulse duration at 1Mb/s data rate.
