Descrizione dell'insegnamento

It is recommended to overcome the exam of Analog Electronics preliminary.

This is a course in RF Microelectronic: it is aimed at providing principles and tools to analyze and design RF analog circuits in CMOS integrated technology.

After the course the student should be able to:

1) Describe the basic RF analog circuits (LNA, Mixer, etc…) and wireless transceiver architectures.

2) Evaluate the performance parameters and discuss complexity issues associated with different basic RF analog circuits and wireless transceiver architecture.

3) Demonstrate circuit analysis capability of not standard circuits.

4) Understand the technology limits in circuit design.

5) Use the simulator to analyse performance of RF analog circuits.

6) Correctly expose a RF circuit study or a wireless transceiver architecture description.

The Course forecasts 30 hours of theoretical lectures about technology description and fundamental RF circuit analysis and wireless architectures. The theoretical concepts are verified in laboratory by using state of the art circuit simulator. 24 hours of laboratory are forecast.

The final (oral) exam consists of two cascaded parts:

1. the first part is based on the discussion about a report on the assigned RF circuit. The circuit must be simulated at the calculator. The student is asked to learn using the simulator, to illustrate the circuit design, to evaluate the performance parameters, and to define the operation of each part of the circuit. It is aimed to verify to what extent the student has gained knowledge and understanding of the use of the circuit simulator and the circuit analysis.

2. the second part is on circuit analysis of one of the RF basic circuits studied during the course or a wireless RF architecture; it is aimed to determine to what extent the student the circuit analysis capability, ability to identify and use data to formulate responses to well-defined problems, correct exposure of the circuit analysis, problem solving abilities and the capacity integrate different concepts.
