Lesson 1 Introduction

- What is electronics?

Science and technique of directing electrons(or any other charge carriers) to perform useful functions

- Electronic devices for directing electrons:

- Directing electrons- Apply potential difference Voltage (V)

- Flow of electrons Current (I)

Resistor (R), Capacitor (C), Inductor (L)

Diode, Transistor

- Useful functions by electronic devices

- Amplification, Filtering, Sampling ....

- Analog, Digital



The first electronic (electric) device

Electromagnetic relay invented in 1835 by Joseph Henry



The first widespread application of electronic(electric) device

Incandescent light bulb in 1880



The first electronic device for ‘circuit’ applications

Why study electronic circuits?

- Semiconductor industry is very important for us:

- Korean semiconductor exports in 2013:10.2% of the total export, 8.2% of GDP

- 2013 market share by sales for Korean semiconductor industry: 15.8%, Second to US

- Electronic circuits are the basic building block for electrical/electronic engineering

- Latest (2015/2Q) market share leaders: Intel (13.6%), Samsung (12.0%), SK-Hynix (4.9%)
