Objectives
This course aims to reinforce an advanced knowledge in analysis and design of radio frequency microelectronic integrated circuits using CMOS technology. This knowledge has to cover not only classical approaches but also has to include more recent and state-of-the-art configurations, demanding original and critical thinking. The student has to acquire skills that enable this, as capacity of cross evaluating information coming from different sources. The student will also have to develop skills to work with the available integrated circuit design frameworks (Cadence) and mathematical software.
The students will develop the skill to solve problems, work in a team and improve their capability to control the available time. Special attention is given to written and oral presentation of the work.
