摘要

A 65nm CMOS configurable transmitter with spur cancellation scheme is presented. Over 10dB spur cancellation is achieved by applying a digital sideband signal at Tx DAC input. The transmitter covers bands from 410 to 2700MHz and supports 2G, 3G and 4G. ACLR is -43dBc at 8dBm and receiver band noise is -160.7dBc/Hz at 4dBm. It consumes 32mW at -8dBm for WCDMA IMT band in SAW-less mode.
