Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: 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.
💡 Hint: Visualize the resistances in series and consider the voltage division.
