Abstract
In this research article, a 1.5-GHz low-noise amplifier and down-conversion double-balanced mixer have been designed for CMOS RF front receiver. It plays a vital role in Global Positioning System (GPS) for increasing the safety and efficiency of flight. Gilbert down-conversion topology has been adopted for the design of mixer, while single-differential topology with matching network has been implemented for low-noise amplifier. The conversion gain of the mixer is 16 dB, noise figure is 12 dB, IIP3 is −5.66 dBm, and 1-dB compression point is 1.369 dBm. The designed circuit is tested at 1.5 V, and the simulation has been carried out with the help of cadence analog design environment with UMC 90 nm technology.
