(Day 7) BJT Curve Tracer

This lab was aimed at analyzing the collector current vs collector voltage characteristics of the BJT. Our analysis focused on the behavior of the BJT when given a step voltage source and a triangle voltage supply. Below is our prediction of what Vout would look like for each given a voltage divider scenario.

Below is the circuit we built containing a 100 ohm resistor, 100 k ohm resistor, two curve tracer voltages, and then the probes for the oscilloscope readings.

Here are the two successful set ups of the variable voltages supplied to the circuit.

Our oscilloscope received the signals below for the output and input voltages.

When we extracted the data from the Analog Discovery and plotted it, we plot almost identical graphs to what we measured using our oscilloscope. This lab was particularly difficult to understand and set up efficiently.
