Aims

To describe to the student, the operation of commercially important semiconductor devices (diodes, BJT, MOSFET) and how these are described by the semiconductor physics.

To enable the student to understand how transistors form key analog circuit building blocks – from single transistor amplifiers to OpAmps. To explain the continued and increasing importance of analog circuits and how the course content relates to the student’s day to day life.

Teaching Rationale And Relationship

PiP sessions provide core material and guidance for further reading, problem solving practice is provided through the online tutorials. Work is further re-enforced through laboratory sessions.

Alternatives will be offered to students unable to be present-in-person due to any public health restrictions. Student’s should consult their individual timetable for up-to-date delivery information

Assessment Methods

The format of resits will be determined by the Board of Examiners
