Abstract :
In this paper, a new design for an Impulse Radar UWB transmitter using an 180nm CMOS process is presented. A 2nd order derivative Gaussian pulse is generated using two Phase Detectors (PDs), which consist of an n-latch and a p-latch to generate a single UWB pulse without any filtering and matches the FCC mask. The Gaussian impulse achieves a very small pulse of 288ps width, 160mVpp amplitude, and consumes about 13μW/pulse. The circuit occupies only 36×42μm2 without PADs.
