Students
taking ECE 411 are to design, using the long-channel process from the book, an
audio amplifier that will be used to drive headphones (like you use to listen
to MP3s). I am looking for you to think about what is needed (e.g., what is the
load presented by the audio head phones, what is your design’s THD, how did you
characterize your design, how does your design perform with power supply noise,
what is the power dissipation, what are the trade-offs?) I do not want to provide a list of
requirements for you then ask you to try and meet them… that is
too easy.
Students
taking ECE 511 are to design a bandgap voltage reference of 500 mV as part of a
voltage regulator that can provide up to 50 mA of current for varying loads.
Assume the voltage regulator’s output voltage is 500 mV. In your report discuss
how to vary the regulator’s output voltage while keeping the BGR output
constant at 500 mV. The design should use the 50 nm models from the book. You
should show how the output voltage changes with VDD, temperature, and load
current. You should discuss the efficiency of your design. It’s a good idea to
determine the important parameters of a voltage regulator, say from a
commercial design via a data sheet, and then discuss, in your report, how your
design compares. Use resistors with TCs of 2000 ppm/C.
Your report, less than or equal to 15 pages, should detail your design considerations, simulation schematics with results, and provide a table summarizing the results. This is not a team effort. I will grade these reports with you present (you will need to come to my office where we’ll go through your design, simulations, and report) so I can ask you questions (yes, your answers will count in your report’s final grade). Simple ways to lose points are to turn in a report longer than 15 pages, or with a gratuitous cover page (provides absolutely no benefit other than taking up space on the hard drive), etc.
Your report is due (should be emailed to me as a PDF) before 6 PM on Friday, Dec. 11. You can
bring your SPICE files with you when we meet.
