This course describes the physical working of the basic semiconductor devices and translates those to electrical characteristics. Based thereon, it treats electronic equivalent circuits and device models. It covers an introduction to semiconductor physics, the pn-junction, the bipolar junction transistor (BJT) and the metal-oxide-semiconductor field-effect transistor (MOSFET).

The physical working is illustrated using schematic diagrams of energy, electric field, electrical potential and concentration, and the principal formulae for simplified devices are treated. Secondary effects in devices are then introduced, with coverage of their physical origins and the effects on the electrical characteristics of the devices.

The device models are derived for DC, small signal and transient behaviour, where a connection is made to circuit simulation.
