What are these semiconductors everyone is talking about? What makes them so special and powerful? Where are they used and how?
We provide answers to these and many more questions in our four MOOCs (Massive Open Online Courses) “Amplifier”, “Digital”, “Resonance” and “Power”. With a mixture of explanatory videos, additional documents, calculation, simulationand practical examples, we teach the most important topics in electronics.

Amplifier

In the first MOOC of our four-part series, we deal with basics of electronics. We cover diodes, bipolar transistors, MOSFETs, transistor circuits, transistor amplifiers, differential amplifiers and operational amplifiers. You should have some prior knowledge in order to understand the content. These are: Ohm’s law, Kirchhoff’s rules, knowledge about alternating and direct currents as well as basics of electrical components (resistor, inductor, capacitor, ideal voltage and current sources).

Digital

The second MOOC dives into the digital part of electronics and explains the steps from a transistor to a digital device as well as important components in the digital domain. Topics covered include CMOS devices, multivibrators, analog-to-digital converters, digital-to-analog converters and basic hardware interfaces.

Resonance

The MOOC “Resonance” is about oscillations - where do they cause problems, where do they solve some and how can they be measured at all? These questions are answered in the topics Laboratory Basics, active Filters, passive Filters and Resonance Circuits.

Power

In the last MOOC we mainly deal with different power supplies and discuss their strengths and weaknesses, also with regard to electromagnetic compatibility. The main focus in this MOOC is therefore on the topics of linear voltage regulators, switched mode supplies and the basics of electromagnetic compatibility.
