| Abstract: | This paper used capacitive cross-coupling technique,have designed a fully differential low noise amplifier with the center frequencies 1561.098MHz for Beidou receiver application based on SMIC0.18μm CMOS technology.Simulation results show that the proposed LNA has a noise figure of 2.045dB,a power gain S21 of 19.684dB,a input reflectivity coefficient S11 and output reflectivity coefficient S22 of less than-13dB and-40dB,respectively,a reverse transmission S12 of less than-40dB,and linearity IIP3 of more than-5.5dBm.The power consumption is 16mW under the DC voltage of 1.8V. |
