Name: _______________________________ EE 3220 Test # 2     SSN: _________________________________    Fall 2001 1.) For a BJT, what order of magnitude are the following parameters: a.) β  ~  10 x x = 1, 2, 3, 4   (circle one) b.) r Π  ~ 10 x x = 1, 2, 3, 4   (circle one) c.) r o  ~ 10 x x = 3, 4, 5, 6   (circle one) d.) r x  ~ 10 x x = 1, 2, 3, 4   (circle one) 2.) Why does the bandwidth of a differential amplifier extend higher, and lower (to DC) than  a simple BJT inverting amplifier?  3.) What major advantage does the current mirror have over the BJT current source? 4.) What advantage does the Widlar source have over the current mirror? 5.) Design a current mirror source drive a differential amplifier.  It must produce I o =0.5mA.  Supply voltage V EE  = -5 Volts.  Assume V f  = 0.7 V.  Compute the power absorbed by Q 2

    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.
