EE 3221 Suhas Patel July 7, 2004 Objective: To build discrete versions of analog circuits ordinarily founding integrated circuits. 1.) Figure 1 Plot the output voltage as a function of the positive supply voltage. Is the slope of this graph exactly 45 degrees? Yes, it is. At what supply voltage does the graph abruptly change? Why? 4.2 V, because the transistor is no longer operating in the constant current region.
2.) Figure 2 Observe the output voltage with a scope, and vary the current in the bottom resistor by changing the negative supply. As the negative supply is varied between -6 and -5V, the output voltage is stable between 0 and 5V. For all other negative supply voltages, the output is unstable and drops below 0V. Can you balance the output between 0 and 5V? Yes, the output is between 0 and 5V for negative supply voltages between -6 and -5V.

### What students are saying

• 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.
