UWB CMOS transmitters for UWB communications
2013 National Conference on Communications (NCC), 2013Development of UWB CMOS transmitters using carrier and impulse techniques is presented. The carrier transmitter designed using a 0.18-µm CMOS process adopts a double-stage switching to enhance RF-power efficiency and reduce dc-power consumption and circuit complexity.

Communications Engineer, 2003
Still in the research stage, ultra wide band (UWB) is promising a wireless revolution. UWB wireless has received increasing interest as a means of transmitting data at a rate in excess of that required for video, and over an ad-hoc network that does not utilise a fixed access point as required by wireless LANs. UWB is a wireless transmission technology
