摘要

An Ultra-wideband (UWB) transmitter is proposed that can correct phase errors in quadrature local (LO) signals automatically without help of baseband processor (BBP), operating from 3 to 9 GHz in 65 nm CMOS. The measured tuning range for sideband rejection is 32.7 dB at 7.7 GHz and 13.6 dB at 8.7 GHz. The measured EVM is lower than -20 dB for all supporting bands and TFCs (Time frequency codes) that are prescribed by WiMedia alliance. The power consumption of the transmitter including LO path and PLLs is 210 mW from a 1.2 V supply.
