No prior knowledge of the subject is required, beyond having taken and performed well in the subjects of the first semester (fall term) of the Master's degree.

Upon completion of this course, students should be able to: - Know and identify the most commonly used modulation types in wired and wireless data communications, and their implications for the transmission and reception stages. - Know the main data communications circuit architectures and their scope of application. - Know the main analog, mixed-signal, and digital circuits most commonly used in the design of data communications integrated circuits, their architectures, and their main components. - Know the methodologies and design flows commonly used in the design of the transmission and reception stages of data communications integrated circuits using advanced CMOS technologies. Analyze second-order effects and non-idealities using these technologies. - Use design, simulation, and layout methodologies and tools for the design of communications integrated circuits. - Evaluate compliance with the requirements of a design or an integrated circuit for a communications channel.
