Electronics Lab Write-Up

During the Fall 2018 semester, I took a course titled “Electronics” at Mount Holyoke College, which was taught by Kathy Aidala. A lot of physics majors take this course in order to fulfill part of the lab requirement for the major. Most of our time in class was spent working on labs that reinforce the concepts in analog electronics that we learn by reading, solving problems for homework, and discussing in a lecture before the lab. The labs we do in class have us building and testing analog circuits that serve a variety of purposes.

The lab I’m sharing in this post is the third lab in the class, and the first one we were assigned to do a write-up on. In this lab, we designed, built, and tested two different circuits, both of which function as a voltmeter. Both of the circuits we built had some parameters that we were required to meet with the design. Before we began, we were given skeleton circuits for both voltmeter circuit designs, meaning that we already had a basic layout of what the circuits should look like. The part of the design that we were tasked with figuring out was what we should use for the specific components of the circuit, such as the values of the resistors, and the model of the op-amp. All of the decisions on these components were made in order to meet the parameters we were given for the circuits. Once we decided on these specifications and had a complete design, we built and tested both of the circuits.

This write-up discusses the specific tasks we were required to do in this lab, and walks through the entire designing, building, and testing process. All circuit designs and drawings, as well as the calculations done to find resistor values are included in the document. The final document was written in LaTeX, and all of the figures were hand-drawn by me.
