Teacher
CASTELLO RINALDO (titolare) - 5 ECTS
MANSTRETTA DANILO - 1 ECTS
Prerequisites
Knowledge of circuit theory and applied electronics (analog) with particular reference to the MOS and BJT transistors, operational amplifiers, Bode plots. Familiarity with the use of the Fourier transform, the Laplace transform, and the complex numbers.
Learning outcomes
The course aims to complete the basic training of the student in analog electronics and to introduce him to the laboratory activity, with the use of the measurement equipment and the circuit simulator Spice. At the end of the course the student should have acquired knowledge on the architectures of multi-stage amplifiers using both MOS and BJT transistors and a deep knowledge of the frequency behavior of the elementary devices and basic circuits; he/she must have a deep understanding of the negative feedback concepts, of the stability problems in amplifiers with feedback and of the techniques to compensate them.
Course contents
Amplification stages with single transistor.
Behavior of the transistors at high frequency, the high frequency equivalent circuit for MOS and BJT. Analysis in the high frequency of the basic stages of amplification. The cascode stage. Differential stage BJT and MOS. Current mirrors. Multistage amplifiers. Output stages: class A, B, AB. Schemes of BJT and CMOS operational amplifiers. The feedback: basic concepts, negative and positive feedback. The negative reaction applied to the amplifiers. Calculation of the loop gain. Stability of amplifiers with feedback. Compensation in frequency.
Teaching methods
Lectures (hours/year in lecture theatre): 31
Practical class (hours/year in lecture theatre): 13
Practicals / Workshops (hours/year in lecture theatre): 20
The lecture are done sing the black board and sometime integrate with foils.
The practical classes are done using the black board and they involves reviewing topics to be known solving examples of analytical calculations. and verifying the knowledge acquired by the students.
The workshops are done with the use of the circuit simulator and the measuring lab equipment.

Assessment methods
The exam is made up of a written part, to be taken at the end of the first module, and of an oral part to be taken at the end of the second modules. The written part accounts for up to 40% of the final score but it is not mandatory. If the student passes the written exams with a score of at least 24/30 the topics of the first module will not be included in his/her oral exam. If the student does no take the written or does not pass it with a score of at least 24/30, the topics of the first module are included in the oral. The written exam includes 2 or 3 circuit problems and about 20 questions with multiple answers. The oral exam varies depending if the student has taken the written or not and on its outcome. In general the oral wants to evaluate the level of understanding of the fundamental topics of the course and the student ability to solve circuit problems. In some cases the oral may include a discussion of the written exam.
