Q9. Determine the current and output impedance

The non-ideal op-amp with gain A=50000, but with infinite input resistance and zero output resistance below is used to increase the overall output resistance of NPN current source below. Find the current I_C and the output resistance, $R_{out}$ R_{out}.

$I_{C} = 14.2 \mu\text{A}$ I_{C} = 14.2 \mu\text{A} , and $R_{out} = 455.32 \text{M}\Omega$ R_{out} = 455.32 \text{M}\Omega

$I_{C} = 16.3 \mu\text{A}$ I_{C} = 16.3 \mu\text{A} , and $R_{out} = 298.45 \text{M}\Omega$ R_{out} = 298.45 \text{M}\Omega

$I_{C} = 18.5 \mu\text{A}$ I_{C} = 18.5 \mu\text{A} , and $R_{out} = 455.32 \text{M}\Omega$ R_{out} = 455.32 \text{M}\Omega

$I_{C} = 18.5 \mu\text{A}$ I_{C} = 18.5 \mu\text{A} , and $R_{out} = 298.45 \text{M}\Omega$ R_{out} = 298.45 \text{M}\Omega

$I_{C} = 18.5 \mu\text{A}$ I_{C} = 18.5 \mu\text{A} , and $R_{out} = 309.77 \text{M}\Omega$ R_{out} = 309.77 \text{M}\Omega
