Unformatted text preview: EECS 314 Fall 2008 Homework set ___ Students name ___________________________ Discussion section # _______ (Last, First, write legibly, use ink) (use ink) Instructor is not responsible for grading and entering scores for HW papers lacking clear information in the required fields above 2008 Alexander Ganago Page 1 of 2 Scores for the HW set: Problem 1 2 3 4 5 6 7 Total Score Problem 1 The Golden Rules applied to a basic Op Amp circuit For the circuit shown on the diagram, do the following: Part 1 (10 points) Write the node voltage equation for V + , first without using the GR and then after applying the GR, in the space below. From the latter equation, calculate the voltage V + in volts and write your answer: V + = ______ V Part 1 2 3 4 Total EECS 314 Fall 2008 Homework set ___ Students name ___________________________ Discussion section # _______ (Last, First, write legibly, use ink) (use ink) Instructor is not responsible for grading and entering scores for HW papers lacking clear information in the required fields above 2008 Alexander Ganago Page 2 of 2 Problem 1, continued The ckt diagram is repeated here for your convenience. Part 2 (10 points) Write the node voltage equation for V , first without using the GR and then after applying the GR, in the space below. From the latter equation, calculate the voltage V OUT in volts and write your answer: V OUT = ______ V Part 3 (10 points) From the the node voltages, calculate the currents I 10 , I 50 , and I 91 in mA and write your answers: I 10 = ______ mA I 50 = ______ mA I 91 = ______ mA Part 4 (10 points) From KCL, calculate the Op Amp's output current I OUT in mA and write your answer: I OUT = ______ mA Verify whether KCL is valid at the ground node. Write your conclusion: Yes / No (circle one) Do not be surprised by the possible violation of KCL: your calculation is incomplete, because the circuit diagram is incomplete, lacking the power supplies (such as 12 V and +12 V), which can carry large currents! Show your work.
