19.6 A 1.9mm-precision 20GS/S real-time sampling receiver using time-extension method for indoor localization

Contrary to conventional continuous-wave communication technologies, Impulse-radio Ultra-Wideband (IR-UWB) allows to have various functionalities such as communication, localization and radar by using a short pulse [1-4]. Also the short pulse occupies an extremely small period of time of the entire transmission period, so it is possible to consider a special technique for digitization of the short pulse which is essential for above applications.
