Report 3: Bipolar Junction Transistor Characterization Name: Lab Section: For this lab, please record the values of current and voltage in the designated boxes. 3.1 Use this table to record and summarize relevant results as you proceed through the lab experiment: for each region of operation, fill in the appropriate entries in Table 1 and compute the resulting β and α values. Parameters Forward Active Saturation Cutoff Reverse Active V BE V BC I B I C β N/A N/A α N/A N/A Table 1: Regions of operations and measurements 3.1.2 Measure V BE and V BC . What is the region of operation? V BE = V BC = 3.1.3 Measure I B and compute β . I B = β = 3.1.4 Calculate α and use the result to calculate I E . What is the measured value of I E . Do the two values for I E agree? 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
