Entry knowledge

The subject knowledge on the Bachelor´s degree level is requested, especially with regard to the principles of analog circuits.

Rules for evaluation and completion of the course

The course evaluation is as follows:

- a maximum of 30 points for two tests during the semester,

- a maximum of 70 points for the final exam, which consists of a written part and oral exam.

Computer exercises are mandatory. Properly excused absence from exercises can be replaced by appointment with the teacher.

Aims

The aim of the course is to teach students the principles of analog integrated circuits design in bipolar technology and the preparation for the follow-up course Advanced methods of analog integrated circuits design- MPC-NAI.

A graduate of the course is able to:

- describe and explain the transistor equation for both basic types of transistors,

- design, simulate and evaluate the results of a several analog integrated circuits (current mirror, reference, simple OTA, output stages),

- design, simulate and evaluate the results of more complex analog integrated circuits, especially operational amplifiers including Rail-to-Rail type, advanced reference circuits and others.

Study aids

For the course there are prepared:

- electronic texts for the lectures,

- an overview of the important equations needed for the design,

- presentations for the exercises.

Prerequisites and corequisites
