Fundamentals of Electronics (ENG2009)

Some extra information about Bipolar Junction Transistors, including DC biasing, fixed bias amplifier circuits and coupling capacitors.

Some notes of the basics of electronics, including a brief history of electronics, electric current, charge, and voltage.

A description of analogue and digital signals and a detailed look at diodes and semiconductors in electronic circuits.

A look at NAND gates as a suitable logic gate in an integrated circuit, and a look at De Morgan's theorems.

A look at the more complex logic gates, such as NAND, NOR and XOR gates. Boolean algebra is covered here, with the mathematical forms written for AND, OR and NOT operations.

A brief overview of electric fields, including Coulomb's law of force and electric field strength, E.

A brief look at Thevenin and Norton's theorems for constructing equivalent circuits.

A look into the history of electronics, and Coulomb's law and the Maxwell equations.

A very brief introduction to the Op-Amp and a case study of temperature controllers.

An overview into potential dividers and Kirchhoff's current and voltage laws.
