1. Electronic Circuits Laboratory EE462G Lab Background, Procedures, and Overview

2. 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 Educational Links http://www.paia.com/~paia/tubworks.htm

3. 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.

4. 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.

6. 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?

16. 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.Print out pages 51 through 55. 2.Put your name on the first page and complete the written exercises. 3.Use the answer key to determine number of wrong responses, put that number on the front page next to your name and circle it. 4.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.
