Circuits and Systems for Radio-Frequency


It is intended that the student, at the end of this course, acquire the knowledge and skills for the analysis and design of transceivers and electronic systems for modern wireless communication using monolithic integrated circuits like "System on Chip" (SoC) and VLSI circuit technology, namely CMOS technology at nano and microscale. In summary:

- Obtain knowledge about radio-frequency (RF) integrated electronic systems and respective architectures

- Be able to analyze and characterize an RF system and understanding the limitations of current technologies

- Analyze and design the fundamental building blocks of a digital radio transceiver

- Be able to use software tools (CAD) for simulation and RF design

- Implement and test hybrid software and hardware solutions, using software-defined radio platforms (SDR)

- Relate all the relevant technical information and skills for the success of the project execution.
