History of Electronics
Vacuum Tubes
Developed
by Lee DeForest (1906)
Used in amplifiers and switching devices
Led to spread of radio broadcasting
1920’s, Television 1930’s, electronic
computers 1940’s

History of Electronics
Solid-State Transistors
 Developed by William Shockley, John Bardeen, Walter
Brattian (Bell Labs) (1947)
 Similar applications as vacuum tube except it requires less
power, has a lower manufacturing cost, performs more
robustly, and could be miniaturized.

History of Electronics
Integrated Circuits (ICs)


Developed by Jack Kilby (TI), and by Noyce and
Moore (Fairchild Semiconductor) (1958).
Multiple transistors, resistors, and capacitors,
fabricated on a single wafer (chip) and could be
made very small.

Nonlinear Device Characterization

To measure nonlinear device characteristics, voltage/current
amplitudes are swept over input terminals while measuring
current/voltage across output terminals (analogous to sweeping
frequencies in linear RLC circuits while measuring amplitude and
phase changes between input and output – What is this
characterization called?).

Curve tracers systematically sweep voltage amplitudes over two
terminals of a device while measuring the resulting current. The
current-voltage relationships is referred to as the transfer
characteristic (TC) curve of the device.

Why is the TC NOT a good model for linear devices? What would
the TC curve or an ideal resistor look like?

Special Assignment 1
Download and read through tutorial on oscilloscopes (~50 Pages), “The
XYZs of Oscilloscopes”
http://www.tek.com/Measurement/App_Notes/XYZs/03W_8605_2.pdf
1.

3.
4.
Print out pages 51 through 55.
Put your name on the first page and complete the written exercises.
Use the answer key to determine number of wrong responses, put that number on the
front page next to your name and circle it.
On a separate sheet of paper, briefly describe (10 to 15 sentences) how an analog
oscilloscope displays a periodic waveform. Assume the trigger is set to the same
channel as the periodic waveform being displayed. Be sure to clearly describe the
relationship between the trigger, oscillating signal, and CRT sweep rate. The reader
should have a good idea why a periodic waveform appears stationary on the
oscilloscope. You can sketch diagrams if that helps your explanation.
Attach all pages together and hand in at the beginning of the next lecture period. The
assignment grade will depend on completing 1 through 3 and the quality of the
explanation in 4.
