Abstract

BeiDou Navigation Satellite System is an important national space-time infrastructure and an important tool for realizing social informatization. BeiDou satellite navigation system has been widely used in transportation, hydrology, meteorological monitoring, and other fields since it provides services. At the same time, the BeiDou satellite navigation system also needs to be further applied in ground navigation. Given the domestic situation, the best practice place is the high-speed field, such as the wide plain, highways, and so on, and the focus is to design a low noise, low power consumption, broadband navigation satellite receiver frequency synthesizer. Considering the selection of frequency points and loop bandwidth of the navigation satellite, this paper selects the phase-locked fractional frequency synthesizer. The linear model of the system is established. After introducing noise, the phase noise model of the system can be obtained. In this paper, the 65 nm CMOS process is used to design and realize dual-mode broadband VCO, decimal frequency divider, frequency discriminator, charge pump, automatic frequency band selection circuit, and loop filter. After simulation verification, the design index is completed.
