A PA for MBOFDM-UWB and IR-UWB transmitters

2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS), 2015
This paper describes the design of 4.2 to 5.9 GHz CMOS power amplifier (PA) for applications in ultra-wideband (UWB) commuincations. The PA operates in the linear region over the input range of −12 dBm and delivers an output power of 6 dBm. The post layout simulations indicate the power added efficiency (PAE) is more than 35% at 5 GHz frequency and ...

Detecting UWB Radar signals with UWB communication interference

2014 IEEE Military Communications Conference, 2014
Ultra wideband (UWB) technology has been widely researched for both radar and communication systems. However, detecting the presence of a signal is essential and challenging for many applications. In this paper, we propose a novel detector for UWB radar signals with UWB communication interference by exploiting the signal cyclic features. A single-cycle

Multiband UWB transceivers

Proceedings of the IEEE 2005 Custom Integrated Circuits Conference, 2005., 2006
This paper presents the design of UWB transceivers from both system-level and circuit-level perspectives. Following a detailed analysis of the impact of RF imperfections on the performance of the system, we review a number of transceiver and synthesizer architectures that can satisfy the MBOA UWB standard requirements.

UWB ranging accuracy

2015 International Conference on Systems, Signals and Image Processing (IWSSIP), 2015
The accuracy of ranging of commercially available ultra-wide-band radio module was evaluated. Such modules are capable of very precise measurements of Time of Arrival of RF signal and consequently very precise range measurements or localizations. We measured and compared the distances with the reference distance using one of these commercial modules ...
