Descrizione dell'insegnamento

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

The course is aimed at providing principles and tools to analyze and design analog circuits in CMOS integrated technology.

 

After the course the student should be able to:

1) Describe the basic analog circuits (bandgap reference, current mirrors, differential couple, Miller opamp, class A and class AB output stages, etc…).

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

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 analog circuits.

The Course forecasts 30 hours of theoretical lectures about technology description and
fundamental circuit analysis. 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 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 basic circuits studied during the course; 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, problem solving abilities and the
capacity integrate different concepts and tools.
