A 0.5-V ultra-low-power non-coherent impulse radio UWB receiver

摘要

A non-coherent 10Msps Ultra-Wideband (UWB) receiver using 3.1-5GHz pulse position modulation (PPM) signaling is implemented in a 65 nm CMOS process. The receiver is mainly comprised of low noise amplifier (LNA), squarer, integrator and comparator. All RF and baseband circuits operate at 0.5-V power supply. The chip area is 1.1mm×1.0mm. Total power dissipation is 7.44mW and 0.8nJ/bit can be achieved when data rate is 10Msps.
