| Resumo: | This Master’s Thesis presents the design of a Radio Frequency (RF) front-end receiver operating in the 2.4-2.5 GHz ISM band, targeting integration in low-power wireless communication systems. The proposed architecture comprises a Low-Noise Amplifier (LNA), a Voltage-Controlled Oscillator (VCO) and an active Mixer, all implemented in a 65 nm CMOS technology. The design process includes schematic simulations with realistic device models, and variability analysis through corner and Monte Carlo simulations to ensure robust performance under PVT variations with compensation techniques. Layouts for all blocks and the full front-end were developed, applying techniques to improve symmetry, matching and parasitic management. Although post-layout simulations were not completed due to layout verification limitations, the design flow provides valuable insights into the challenges and trade-offs of RF circuit implementation in advanced technologies. The results demonstrate the feasibility of the high-frequency front-end integration and establish a foundation for future development and potential fabrication. |
