EET 120 Semiconductor Devices Unit 2 Lab Assignment Instructor: Dr. Alireza Hassanzadeh By: Kellen Munden Honor Pledge : I pledge to support the Honor System of ECPI. I will refrain from any form of academic dishonesty or deception, such as cheating or plagiarism. I am aware that as a member of the academic community, it is my responsibility to turn in all suspected violators of the honor code. I understand that any failure on my part to support the Honor System will be turned over to a Judicial Review Board for determination. I will report to the Judicial Review Board hearing if summoned.

Abstract This lab contained two chapters, for the first chapter contained three circuits to analyze. For the first we were to find the minimum and maximum load current for a Zener diode circuit, for the second we were to find the output voltage for the Zener limiting circuits and for the final circuit we were to find the fault. For the second chapter we had four circuits to analyze. For the first we were to find the currents and voltages in a BJT circuit, for the second we were to determine if a transistor was in saturation, the third we were to determine the amplitude of a square wave to saturate a transistor, and for the final circuit we were to find the fault. Introduction This lab contained two chapters, the first chapter dealt with Zener diodes and the second chapter dealt with BJT circuits. For the first chapter in this lab for the first circuit we were to find the minimum and maximum currents in the Zener diode circuit that will maintain regulation in the circuit, and to find the minimum value of R L that can be used. We used ideal Zener diode assumptions and to find the maximum current we used I Z(max) =V IN -V Z /R. We then found the maximum load current using the equation I L(max) =I T -I ZK . Finally, to find the minimum load resistance we used Ohm’s Law which is defined as R L(min) =V Z /I L(max) . For the second circuit we used the oscilloscope to measure the output voltages for the Zener limiting circuits. For the third circuit we used the DMM to measure certain values in the circuit to see if we could identify the fault in the Zener diode circuit. For the second chapter of this lab for the first circuit we were to find all currents and voltages from the base, collector and emitter of a BJT circuit. To find the current at the base we used the equation I B =V BB =V BE /R B , for the current at the collector we used the equation I C DC I B , and for the current at the emitter we used the equation I E =I C +I B . To find the voltage at the collector-emitter junction we used the equation V CE =V CC -I C R C . Then to find the voltage at the
