3 cards from this section. Quick, good the night before a test.
What is the formula for calculating the voltage gain in a common source amplifier?
Recall the roles of g_m and R_D in the formula.
What does g_m represent in the context of amplifiers?
Think about how sensitive the amplifier is to input voltage.
What does the voltage gain (A) represent in an amplifier?
Think about how much the amplifier amplifies the signal.
True or False: Parasitic capacitance increases the effective input capacitance according to the Miller Effect.
Consider how feedback can modify circuit variables.
A Common Source Amplifier has a transconductance of 2mA/V, a drain resistance of 2.5kΩ, and an input resistance of 1kΩ. Calculate the voltage gain and discuss how changing load resistance affects output voltage.
Think about the interactions between resistances at the output.
What are the implications of significant parasitic capacitance at the input of a high frequency Common Source Amplifier? Provide a detailed explanation.
Link your explanation to feedback and its effects on capacitance in amplifiers.
