IR-UWB BPK transmitter optimized for maximum distance of transmission

This paper describes the implementation of an Impulse-Radio Ultra-Wide-Band Bi-Phase Keying (IR-UWB BPK) transmitter which has been optimized to achieve the maximum distance of transmission while working within the power limits specified in FCC UWB specification. A theoretical analysis is performed to obtain the relationship between the output amplitude and data rate of the transmitted signal. The design is implemented in a 180nm CMOS process. The post-layout simulations, with extracted R, L and C parasitics, are presented. The output peak amplitude of the transmitter is 0.7 V at a maximum data rate of 700 Mbps. The total area of the chip is approximately 1mm² including electrostatic discharge (ESD) diodes protection.
