ECE 323 Electronics III Study Guide #5 28 April 2014
Quote of the week: “You can study textbooks and simulate for weeks, but until
you actually build the circuit and hook it up to power supplies and signal
generators, you don’t even know what it is that you don’t know.”
Tasks for this week: Take a mid-term inventory of Course Outcomes and
determine the topics covered in the mid-term.
Detailed design of VCO including design of resonator, different oscillator
topologies, and Kvco. Example Hartley, Colpitts, and Pierce oscillators.
Design of AC op-amp and transistor amplifiers using coupling and Feedback
capacitors.
Getting Analog signals into and out of Logic Gates
Analyze and design single transistor and op-amp AC and DC feedback networks
A catalog of sinusoidal waveform generators
Logic families and gates
Electronic multiplier/phase detector: Gilbert Cell, Diode Ring, and Exclusive OR
Interfacing between analog and digital circuits
Phase locked loop -- acquiring lock
Phase locked loop -- locked
Applying Electronics Engineering course work to open-ended projects
Introduction to Electronic Prototyping
This week: begin preparation for the mid-term exam. Next week’s study guide
will be mid-term preparation, listing topics, example questions, etc.
This week in lab: Start Laboratory 2--introduction to the POS-100 voltage
controlled oscillator. Continue exploring breadboarding and prototyping. Be
able to sketch a schematic and construction details for powering up the POS100 VCO in the lab kit and looking at the output on the Oscilloscope and Spectrum analyzer with a 50 ohm load, starting from a blank sheet of paper.
Next Week is Lab evaluation Week. Be ready to demonstrate working hardware,
interconnected phase detector and VCO, and lock with the oscilloscope and
Spectrum analyzer. Labs 3 and 4 assignments will be based on demonstrated
capabilities of Spring 2014 ECE323 class.
