4 cards from this section. Quick, good the night before a test.
What does voltage gain represent in an amplifier?
Think about how an amplifier changes the input signal.
List the components that affect the voltage gain in a common emitter amplifier.
Recall the factors we discussed in class.
What is the formula for calculating voltage gain in a common emitter amplifier?
Look for a formula including both R_E and R_C.
True or False: Increasing the emitter resistance will increase the voltage gain.
Recall the effect of R_E on gain from our discussion.
Design a common emitter amplifier with a desired voltage gain of -10. Given the transconductance g_m is 0.01 S, determine the required values of R_C and R_E.
Start with assumed R_E values and calculate R_C accordingly.
Evaluate how the choice of R_E affects both gain and stability in the amplifier circuit under varying temperature conditions.
Consider how gain and biasing interact and affect overall performance.
