一种基于CMOS的宽带抗阻塞射频接收机设计
Design of a broadband blocker-tolerant RF receiver based on CMOS
摘要
Abstract
Aiming at the problem of single frequency band and low integration of traditional RF receivers in multi-band and multi-mode wireless communication applications,a broadband blocker-tolerant RF receiver based on Complementary Metal Oxide Semiconductor(CMOS)with N-path filtering and receiver integration technology is proposed.The receiver integrates an N-path mixer and baseband filter.Layout testing under 65 nm CMOS process shows that the receiver provides more than 60 dB of out-of-band rejection outside of the 5 MHz baseband bandwidth and frequency tuning range of 0.25~2.5 GHz.The front balun's low-noise amplifier achieves a receiver conversion gain of 46 dB while reducing the overall Noise Figure(NF)to 3.1~4 dB.The receiver also achieves 24.5 dBm Out-of-Band Third-order Intercept Point(IIP3)and consumes only 26 mW.关键词
