An LC filter based UWB pulse generator to be implemented in IBM 0.13 µm CMOS technology is presented. A 6 th order elliptical filter approximation of the Federal Communications Commission (FCC) Ultra Wide Band (UWB) mask is used to generate the transfer function. The filter order is chosen based on mask filling efficiency, component spread and circuit complexity. The impulse response of the filter is used to generate the UWB pulse. The current consumption is 2.8 mA at 1.5V, at a pulse rate of 200 MHz. The bandwidth of the UWB pulse is 4GHz. The pulse generator operates over the military temperature range (-40°C to 125°C). Monte Carlo analysis simulation results show an acceptable effect of both mismatch and process variations on the UWB pulse.
