Students get the fundamental understanding of technologies underlying electronic digital systems. The understand the basic theoretical models and principles of functionality of transistors, gates, circuits, and conductors. They are able to design simple circuits and evaluate circuit parameters. They understand the differences between analog and digital modes of electronic devices.


High-School level of mathematics and physics.

Study Objective:

The aim of the module is to teach the fundamentals of digital and analog circuits, as well as basic methods of analyzing them. Students learn what do computer structures look like at the lowest level. They are introduced to the function of a transistor. They will know why processors generate heat, why is cooling necessary, and how to reduce the consumption; what are the limits to the maximum operating frequency and how to raise them; why does a computer bus need to be terminated, what happens if it is not; what does (in principle) a computer power supply look like. In the labs, students will perform measurements on actual circuits. They will also design circuits and verify some of their designs hans-on. Mathematica software is used to solve problems.
