Abstract :
A non-coherent 0-to-16Mb/s UWB receiver using 3-to-5GHz subbanded PPM signaling is implemented in a 90nm CMOS process. The RF and mixed-signal baseband circuits operate at 0.65V. Using duty-cycling, adjustable BPFs, and an energy-aware baseband, the receiver achieves 2.5nJ/b and 10-3 BER with -95dBm sensitivity at 100kb/s.
