Crediti/Credits

6 CFU

Obiettivi formativi specifici/Objectives

These classes have the following main goals:

- explain the working principle of the circuit blocks used in most VLSI transmitter and receiver systems: low noise amplifiers, power amplifiers, oscillators, mixers and phase locked loops;
- explain and discuss the main methodologies employed for the design of such circuit blocks;
- present some popular TCAD environments for the design of RF circuits and use them for some design problems proposed in the classes.

Competenze acquisite/Acquired skills

- Understanding the behavior and design strategies for RF building blocks.
- Methodologies used for the study of non-linear circuits under periodic/large signal conditions.
