Question

Problem 1 (15 Points) Multiple Choice Problems (only ONE correct answer each. More than one choice will be considered WRONG. 5 points each). 1) The small signal amplifier circuit to the right is a and its main function we discussed in class is A. Common-Base, 50 ohm cable matching B. Emitter Follower, 50 ohm cable matching C. Emitter Follower, voltage buffer D. Common-Base, voltage buffer 2) The small signal condition needs to be satisfied in order to A. Increase amplifier gain B. Reduce amplifier gain C. Reduce non-linear distortion D. None of the above Themodel which assumes a 0.7V voltage across an "ON" Diode is also used in our BJT analysis for simplification. 3) A. Constant voltage drop B. Exponential C. Ideal diode D. None of the above

Explanation / Answer

1. D is right answer as the circuit is of common base, voltage buffer.

2. C is right answer as small signal amplifier amplify input signal with the minimum amount of distortion

3. A is right answer as diode in on state has voltage drop equal to cut in voltage.
