2 cards from this section. Quick, good the night before a test.
What is the primary function of biasing in amplifiers?
Think about how we wanted the amplifier to behave.
What happens to DC currents in small signal analysis?
Consider what we focus on for small signal behavior.
What does biasing in amplifiers primarily affect?
Think about what allows the amplifier to function correctly.
In small signal analysis, we drop which component?
Remember what we want to analyze?
Given a Common Base amplifier with parameters g_m = 100 mA/V and r_o = 1 kΩ, determine the voltage gain assuming an input signal of 5 mV.
Apply the voltage gain formula after identifying the required variables.
Analyze how input impedance is affected when a source resistance of 1 kΩ is coupled to an amplifier with an input resistance of 50 Ω.
Visualize the resistances in series and consider the voltage division.
