A CMOS Carrier-less UWB Transceiver for WPAN Applications

Abstract

A carrier-less impulse-based UWB transceiver (TRX) chipset is presented. The TRX employs high-order pulse transmission with analog pulse-position modulation. Realized in a 0.18μm CMOS process, the TRX achieves a NF in the range of 7.7 to 8.1dB, an IIP3 of -12.3dBm, and a sensitivity of -80 to -72dBm. It consumes 76mW and 81 mW from a 1.8V supply in transmit and receive modes, respectively
