Questions about common emmitter, phase splitter

  1. Mar 16, 2013 #1
    1. The problem statement, all variables and given/known data

    Hi, I have a test and need to prepare with the following questions. Unfortunately, we don't have any material to read in order to prepare. I was hoping that somebody could please help me answer at least some of these questions, or provide me with a source where I can find the answers. I've tried to google the relevant concepts but I still can't find any more answers. Thanks in advance for any help, it would be very appreciated..

    4. What is the cause of the voltage droop? (this question is related to common emitter or asymmetrical amplifiers)

    5. What is the relation between rise time and high limit frequency?

    6. What is the relation between the low limit frequency and the voltage droop?

    9. How can be determined the operation point of the transistor in a common emitter / collector / base configuration in case of a single supply or a double supply?

    10. How to calculate the conduction (g) and hybrid (h) parameters from the operation point data of the transistors?

    11. How to calculate the voltage gain, the input resistance and the output resistance of the basic transistor amplifiers if the g or h parameters of the transistor are known?

    15. How to calculate the voltage gain, the input resistance and the output resistance of the basic transistor amplifiers if the g or h parameters of the transistor are known?

    16. Draw the high frequency hybrid π equivalent circuit of the bipolar transistors, and knowing the operation point data calculate the value of the components in it.

    17. What does it mean „physical parameter”?

    18. What is the effect of the emitter resistance on the high frequency time constants?

    20. What is the effect of the emitter capacitance on the Bode plot of the common emitter amplifier?

    2. Relevant equations



    3. The attempt at a solution
