Learning outcomes of the course unit

The student is able to:
- describe and explain the transistor equation for the two basic types of transistors,
- to design, simulate and interpret the results of a series of analog integrated circuits (current mirror, reference, simple OTA, output stage)
- to design, simulate and interpret the results of complex analog integrated circuit especially operational amplifiers Rail-to-Rail, and more.


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