[Cr:2, Lc:1, Tt:0, Lb:3]

#### Course Outline

• In this course the emphasis will be on practical knowledge and not on teaching electronics as a theory subject. The topics below provide a framework from which the instructor can choose experiments:
• Electronic Devices: Basic concepts of AC & DC current and voltage. Signals(sinusoidal and other) and signal sources. Voltage and current relationships in lumped circuit elements(Resistor, Capacitor and Inductor). Reactance and Impedance. Voltage current sources.
• Passive components. Device principle. Device characteristics( Semiconductor Diode and diac, power diode, signal diode, zener diode, LED photo diode varicap). Electromechanical devices, Indicators, variable components
• Active components: BJT, FET & MOSFET (Device principles, Characteristics, Comparison and applications). Amplifier. Switching. Current source.
• Negative resistance Devices: Unijunction Transistor, SCR, TRIAC.
• Power supply principles: Introduction to Linear and SMPS power supplies, basic principles and differences. Introduction to three terminal regulators (78XX, 79xx and LM317).
• Device applications. Diode applications (Rectification, Voltage regulation, Clipping, Clamping, voltage multipliers). Transistor applications (Amplification, oscillator, current source and Switch). Configurations(pushpull, Darlington, Bootstrapping, Differential amplifier).
• Integrated Circuits. Operational amplifier basics. Applications: Offset null, inverting amplifier, noninverting amplifier, logarithmic amplifier, integrator, differentiator, comparator, active rectifier, current to voltage convertion. Timer IC 555 basics , application as astable, monostable, bistable multivibrator.
• Digital Electronics: Introduction to Boolean Algebra, Number systems, Logic gates. Short project on a design/simulation application involving one of the devices studied using circuit simulator and realise the design on a PCB.
