So lets try to describe it.... What do you think of when you think of ECE?

How many things did you use today that require electricity to operate?

My Broad Definition of ECE The art of utilizing electricity and electromagnetic phenomena to do useful things...

In the past, it was about...

Electric POWER Lighting Motors

And Communication... 1837 1900

Early Radio Technology (circa 1920)

And... Early COMPUTING ENIAC 1946 17,468 Vacuum Tubes 7,200 Crystal Diodes 1,500 Relays 70,000 Resistors 10,000 Capacitors 5,000,000 Hand Soldered Joints 30 Tons 1,800 sq ft 150 kilowatts

1947 Revolution! The Transistor Walter Brattain John Bardeen William Shockley

1958 Jack Kilby Invents the Integrated Circuit Texas Instruments

What is so significant about the Transistor and Integrated Circuits?

Modern Integrated Circuit Millions (billions) of Transistors on a single die.

So, let’s pick a modern electronic device and dissect it...

ONE Modern Example...A Cellphone Q: How many technologies are represented here? http://r3.whistleout.com.au/public/images/blog/2012/07/samsung_galaxy_s3_review_10.jpg

How many different technologies are utilized in a cell phone?

Here’s a Partial List Related to ECE Display Technology LCD Displays Touch Screens LED Backlighting Battery & Charging Technologies Lithium Ion Efficient AC-DC Power Supplies Computer Technologies Microprocessor / Microcontroller Memory (Cache / SIM Card) USB Interface Audio Technology Class-D Audio Amplifiers A-to-D and D-to-A Converters Filter Technology Microphone Technology Camera Technology CCD Imaging Sensor Technologies Touch Screen Switches Biosensors Wireless Technologies RF Antennas / RF Transceivers WiFi / Wireless Routers Blue Tooth (local wireless) Cellular Network Technology CDMA vs. GSM Cell Towers Base Stations Packet Switching Networks

And each of these areas represents a potentially different career path within ECE... Why?

And that’s just ONE product – a Cell Phone...

So how do you choose?

One Approach...

“Pick a problem in the world and dedicate yourself to solving it “Pick a problem in the world and dedicate yourself to solving it... The rest will work itself out on it’s own.”
