Electronics Design Laboratory

ECEN 2270

This course is an introduction to the analysis, modeling, design, and testing of analog electronic circuits in a practical laboratory setting. The laboratory is centered around a robot platform and includes design, Spice simulations, prototyping and testing of the circuits necessary to drive and remote control the robot.

  • An introduction to prototyping, simulations and testing of analog circuits
  • Speed measurement circuits and measurement and modeling of robot DC motor characteristics
  • Electronic drives for robot DC motors and speed control circuits
  • Robot speed and position control using a microcontroller
  • Remote control using radio-frequency (RF) circuits
  • Design project

The required prerequisite for this course is ECEN 2250 Introduction to Circuits & Electronics. The required co-requisite is ECEN 2260 Circuits as Systems.

    Grading and related policies

    • The course is organized into six experiments. Each experiment includes graded components consisting of an in-lecture quiz, individual and group demonstrations, and a written group report. The grade weightings are listed on the course D2L website.
      • Written reports must be submitted to the course D2L dropbox.
      • No late work is accepted
      • All unexcused absences will result in a reduced report grade (adjusted individually)

    Additional notices

    • This course strives to provide the student with a variety of specific learning outcomes. These include the student outcomes identified by ABET, and adhered to by the ECEE department, related to the skills, knowledge, and behaviors that students acquire as they progress through the program. The specific Student Outcomes can be found here.
    • If you qualify for accommodations because of a disability, please submit to me a letter from Disability Services in a timely manner so that your needs may be addressed. Disability Services determines accommodations based on documented disabilities. (303-492-8671, Willard 322)
    • Every effort will be made to reasonably and fairly deal with students who have serious religious observances that conflict with scheduled exams, assignments, etc. Please notify the instructor well in advance, so that there is time to make adequate arrangements. The Boulder campus policy can be found here.
    • All students will be expected to comply with the Boulder campus honor code. For more information, see http://www.colorado.edu/honor-code
    • Students and faculty each have responsibility for maintaining an appropriate learning environment. Those who fail to adhere to such behavioral standards may be subject to discipline. Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with differences of race, culture, religion, politics, sexual orientation, gender, gender variance, and nationalities.
