Abstract
This paper designs an interpolator for a high speed ultra wide bandwidth (UWB). The UWB wireless technology will play a key role in short-range wireless connectivity supporting very high bit rates availability, low power consumption, and location capabilities. Because the UWB needs high operating speed, a cubic interpolator based on variable parameters for the UWB needs to be operated at a high speed. In order to improve an operating speed, the modified cubic interpolator is based on both a parallel processing and a pipelining in the existing interpolator simultaneously. Experimental results show that a maximum operating speed and period of the proposed interpolator using Stratix II EP2S60F1020C3 is 102.42MHz and 9.764ns, respectively. Compared to the conventional interpolator, the designed cubic parameter interpolator has been improved more than about 190%.
