Broadband anti-blocking radio frequency receiver based on N-path filtering technology

The invention relates to a broadband anti-blocking radio frequency receiver based on an N-path filtering technology. The broadband anti-blocking radio frequency receiver comprises a multi-stage N-path filtering and mixing circuit, a baseband amplifier circuit and a four-phase non-overlapping clock generation circuit, the multi-stage N-path filtering and frequency mixing circuits are cascaded and used for amplifying useful signals, filtering blocking signals and converting high-frequency signals into low-frequency signals; the baseband amplifier circuit is used for amplifying the signal after down-conversion; the four-phase non-overlapping clock generation circuit is used for providing a non-overlapping clock for controlling the multi-stage N-path filter and the frequency mixer. The receiver has the characteristics of full integration and high linearity, and is easy to receive signals of different frequency bands through frequency tuning. 本发明涉及一种基于N路径滤波技术的宽带抗阻塞射频接收机，包括多级N路径滤波及混频电路、基带放大器电路以及四相不交叠时钟产生电路；所述多级N路径滤
