This research is focused on timing correlation of low d ata rate IR-UWB for medical sensor design in Body Area Net-w ork (BAN). A passive and an active correlator are compared by multiplying the incoming pulse with three different templates, namely sine wave, clock and 5 th derivative Gaussian pulse. Their individual performance and resistance to interference have been studied in detail. The intermittent characteristic of UWB pulse makes the passive correlator appropriate to reduce overall power consumption. The Gilbert Cell based active mixer has higher output level with increased power consumption.
