Double Degree in International Computer Engineering and Management of Business and Technology

Analog Electronics

Description: 

Applications are basically studied in the field of the analog electronics: negative feedback, stability, operational amplifier, oscillators, and power amplifiers. Practices consist of the theoretical study of the design´s different electronic blocks, by means of their simulation on PSpice, as well as the on board implementation of the design.

Methodology: 

The methodology used in this subject separates lessons in two kinds: theoretical and practical. Theory lessons basically consist of theoretical explanations of the subject´s contents and solving problems related to these contents. In each theory block, problems are posed for the students to resolve at home and hand in to the teacher in order to do a continuous evaluation. Some problems are also posed in class for students to resolve them in situ and actively participate in class. Practical lessons have the intention of giving practical examples of that explained in the theoretical classes. In order to do the practical classes in the Electronics laboratory, students are divided into smaller groups with a teacher for each group. These lessons are attended and are always done with the teacher, for any advice they may need. Students do the practices in pairs.

Each one of the practices consists of various sessions. In the first sessions the teacher goes through the theoretical contents necessary to do the practices, and the assemblies which need to be done. The following sessions are for the student to simulate all the suggested assemblies with the computer and the adequate software. Once this is studied, and with a clear idea of the final design, the last sessions are for the practical assembly. This assembly and its technical report must be defended before the teacher. For the student´s better performance he/she has the possibility of personalized consultations on the subject, at a contents level, or on any other related matter (studying methods, planning, practical designs, problems correction…)

Evaluation: 

This subject is divided in two different parts: a theoretical and a practical part.

Each part is evaluated separately and each one has to be passed in order to pass the complete subject.

If both parts are approved, the subject's final grade will be the arithmetic addition of the Theoretical grade (out of 10) and the Practical grade (out of 2).

Evaluation Criteria: 

The student must:

  1. Prove to have the basic knowledge related to the subject
  2. Know how to resolve and design any problem posed in the field of analog electronics
  3. Have the capacity to plan all the tasks related to the practices in order to hand them in on the dates established for each one of the parts forming the practices.
  4. Be used to working with the computer and to systems analysis and design on the computer, as a step previous to the implementation of any design
  5. Have the capacity for organization in order to work and promote team work. In the same way, team work provides the possibility of developing the capacity of applying the knowledge acquired to the practical design and being able to solve any problem.
  6. Have the capacity for synthesis in front of all the information received, in order to choose the best elements for the realization of the practices.
