Electronic Systems and Design

ENGN2218 Electrical Systems & Design builds directly on ENGN1218 Introduction to Electrical Systems by developing the students' understanding of the principles and operation of advanced electronic circuits and devices (bipolar junction transistor, operational amplifier, filters, digital logic gates, ADC and DAC, 555 Timer and Instrumentation amplifiers). It also emphasizes the importance of modelling the behaviour of complex electronic circuits and devices using systematic mathematical techniques. PSPICE is used extensively in the analysis and design. Specific topics include: - Bipolar Junction Transistors: Basic BJT concepts and circuit models, BJT Amplifiers (bias circuits, small-signal and large-signal equivalent circuits), BJT Common Emitter and Common Collector amplifiers, Cascaded BJT amplifiers. - Op-amp: Op-amp characteristics, closed loop and open loop gains, Schmitt trigger. - Steady State Sinusoidal Analysis: complex numbers, phasors, impedances, complex power. - Op-amp Filters: Transfer functions, Bode Plots, First order active filters (low-pass and high pass). - Digital Electronics: Number systems, Boolean algebra, Logic gates, Combinational logic circuits, Karnaugh maps, Combinational logic circuit design. - Special topics: Analog to Digital Converters (ADC), Digital to Analog Converters (DAC), 555 Timer, Instrumentation Amplifiers.
