This course introduces the analysis and design of fundamental analogue electronic and introductory digital electronic circuits. It also provides an understanding of the basic circuit properties and applications of different electronic devices (diodes, bipolar junction transistor, operational amplifier and logic gates). The primary aim is to provide a solid foundation for students in the field of electrical engineering.

Specific topics include:

• Electric circuit analysis: first order RC and RL circuits.
• Diodes: Basic diode concepts and diode circuit models, applications (rectifier and wave shaping circuits).
• Bipolar Junction Transistors: Basic BJT concepts and circuit models, BJT Amplifiers (bias circuits, small-signal and large-signal equivalent circuits).
• Field Effect Transistors: Basic FET concepts (NMOS and PMOS), FET circuit models and applications.
• Introduction to Operational Amplifiers: Ideal op-amp, Basic Op-amp configurations, First order active filters (low-pass and high pass).
• Introduction to Digital Electronics: Number systems, Boolean algebra, Logic gates, Combinational logic circuits, Karnaugh maps.

PSPICE is used extensively in the analysis and simulation.
