History of Electronics

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

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 for an ideal
  resistor look like?

Assignment Part 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
• 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 lab period. The assignment
  grade will depend on completing 1 through 3 and
  the quality of the explanation in 4.
