摘要

This paper presents the first reported highly linear, power efficient, and wideband X-band transmitter (TX) with a fully integrated power amplifier (PA) in 65 nm bulk CMOS. The TX features baseband current-bleeding, headroom-efficient and low-noise current mirror, harmonic trapping on the upconversion mixer, wideband PA inter-stage matching (IM), bulk-floating connection on the PA output stage, as well as efficient output matching network. Fabricated in 65 nm bulk CMOS, the TX achieves 1dB bandwidth from 8.5 GHz to 11 GHz, >19 dBm OP1dB with 24 % system efficiency, and -134.9/-135 dBm/Hz out-of-band noise for the lower and upper sidebands. To the author's best knowledge, this work is the highest efficiency X-band, PA-included TX in CMOS at OP1dB.
