【 摘 要 】

Low noise amplifier (LNA) is a ubiquitous Radio Frequency (RF) component employed in the global navigation satellite system (GNSS) front end receiver to amplify the degraded RF signals captured by the antenna to the desired level. GNSS LNA boosts the desired signal power by adding minimal noise and distortion to mitigate the impact of noise added by subsequential components of the RF receiver chain thereby improving the overall signal-to-noise ratio (SNR) and the overall performance of the system. This paper explores the various GNSS LNA topologies that improve the system's overall performance with minimum power consumption, low noise figure (NF), high gain, good input-output matching, stability, and linearity. The outcome of this research work would help to design a successful LNA for enhancing the performance of the GNSS receiver.
