Fundamentals of Electronics (ENG2009)

A detailed analysis at the diode applications, including rectifiers, battery chargers and zener diodes, with graphs and equations to assist in explanations.

Zener diode characteristics as a graph, and zener diode characteristics. Transistor applications and BJT construction, along with npn and pnp transistors. The focus will be on npn only.

A look into diode applications, including diode characteristics graphs and diodes in forward bias, reverse bias and the reverse breakdown region.

A look at the Bipolar Junction Transistor, including the cutoff, linear and saturation regions.

A look into transistor operation limits and transistors as switches, with a few example questions.

A brief overview of diodes and semiconductors.

A brief look at the summing Op-Amp circuit, before moving on to digital electronics. Definitions of analogue and digital signals, and the AND, OR and NOT logic gates.

Some brief notes including an example question on inductive load drivers, and some notes on logic gates and op-amps

An overview of operational amplifiers and their circuits, including the golden rules.

A practice question of the basic transistor amplifier circuit. AC signal analysis can be used to study the AC amplifications of BJTs (Bipolar Junction Transistors).
