摘要：
An enhanced N-path filter-based receiver with 80-dB/decade RF selectivity and distortion cancellation is presented to improve channel selectivity and resilience to adjacent channel blockers. An integrated circuit prototype is fabricated in 28-nm CMOS as proof-of-concept and characterized. The front-end, capable of operation from 0.2 to 3.5 GHz, shows a close-in roll-off of 80 dB/decade. It achieves a record adjacent channel B1dB of +8 dBm, alternate channel B1dB of +10 dBm, and adjacent channel IIP3 of +23 dBm. © 2018 IEEE.
