Electronics engineering, or electronic engineering, is an engineering division which utilizes non-linear and active electrical components such as electron tubes, and semiconductor devices, especially transistors, diodes and integrated circuits to design electronic circuits, devices and systems.

Typical undergraduate syllabus or the subjects for Electronics engineering are as follows:

Apart from electromagnetics and network theory, other items in the syllabus are particular to electronics engineering course.
