摘要/Abstract：
This paper describes circuit techniques for robust IR-UWB receiver design for high data rate centimeter range communications. For high data rate transmission, multiple frequency bands are utilized to increase transmission power for improved link margin, in the receiver design, a multiband LNA, a fully differential squarer, and a high speed parallel interlacing integrator are developed for high speed data recovery without requiring a high performance analog-to-digital converter. In this work, a 500Mb/s 12.5mW UWB receiver is designed in 65nm CMOS, achieving energy efficiency of 25pJ/b. Simulation results show that narrowband interference from the frequency band of 802.11a wireless standard whose power spectral density is 70dB higher than target sensitivity of -65dBm can be tolerated.
