Pre-Requisite Knowledge

Circuit Theory and Analysis

Summary of Content

The aim of this module is to provide the student with knowledge of the characteristics and parameters of various discrete and integrated circuit electronic devices. The aim of this module is also to enable the student to understand the operation and design of a range of electronic circuits including amplifiers, filters, oscillators and timers.

Syllabus

The teaching syllabus will cover the following areas: Transistors: The characteristics and small-signal parameters of bipolar junction and field-effect transistors; the common-emitter amplifier - biasing, load lines, impedances, gains and frequency response; the common-emitter amplifier with a tuned-circuit load - frequency response, resonant gain and bandwidth; feedback - negative and positive, classification and characteristics of various types of negative feedback; the common-collector amplifier - impedances and gains. Oscillators: The Barkhaussen criterion, R-C and L-C oscillators; frequencies of oscillation and maintenance conditions; the characteristics of piezoelectric crystals; crystal-controlled oscillators. Operational Amplifiers: Characteristics and parameters - voltage gain/frequency response, bias currents, offsets, common-mode rejection ratio, impedances and dynamic characteristics; operational amplifier circuits - inverter, non-inverter, inverting summer, inverting integrator and comparator/Schmitt trigger; the transfer of functions of various passive and active circuits. Active Filters: Advantages over passive filters, ideal low-pass, high-pass and band-pass responses; design of second order Butterworth and Chebyshev filter circuits. Applications of the 555 Timer: Mono-stable circuit, a-stable oscillator and voltage-controlled oscillator. Optoelectronics: Introduction to the wave properties of light; light emitting diodes, lasers, photodiodes, phototransistors, opto-couplers; optical fibers.

Teaching / Learning Strategy

The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on emerging technologies. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
