Calculate the voltage gain and input impedance for a common collector amplifier given: β = 120, I_C = 1 mA, and r_o = 150 kΩ.
💡 Hint: Convert I_C to g_m first.
In a scenario where the load capacitance increases and source resistance is significant, analyze how this affects the bandwidth of the amplifier.
💡 Hint: Remember f_cutoff = 1 / (2πRC); how do varying R and C affect this?
