Abstract :
This paper conceptualizes an integrated clock less and multipath-robust Impulse Radio-Ultra Wideband (IR-UWB) transceiver for communication and localization purposes. The ranging scheme is based on the use of the same transceiver installed both in the anchor and in the mobile nodes, for a Two-Way-Ranging (TWR) Time of-Flight (ToF) estimation. The transmitter and receiver are implemented in a 130 nm RFCMOS technology. This paper presents the block scheme of the transmitter and the receiver, as well as the ranging scheme, prior to the chip validation and test.
