Name:_________________________________ Fall 2002 SSN:____________________ Test # 1 1. Sketch the output signal given the transfer characteristic of an inverting amplifier  and a plot of the input signal below. 2. Find the power delivered to the load.  How could we improve the power gain of  the overall system?

3. Perform the DC bias analysis for the circuit below.   4. Choose values for R 1  and R 2  that will bias V C  close to 0 volts.  What is the  approximate gain of the circuit?  What is the EXACT gain?
5. Compute the gain for the circuit below. 6. 7. g 8. g 9. Why is the circuit in problem # 5 a better IC solution than a single BJT amplifier  with a bypass capacitor?

Unformatted text preview: 10. FET’s are useful as inverting amplifiers, but not when they have resistive loads connected to their source. Why are FET’s with resistive loads not ideal? 11. Show mathematically that the following circuit provides a linear amplification of v in . 12. The FET has an infinite input impedance. What advantage does this give us in an amplifier circuit? 13. If LSU were to play Virginia Tech next week, who would win? (Hint: VT is ranked # 3 and LSU is ranked # 12) IF you are not sure how to answer this, ignore it. This problem doesn’t really count for anything....
