Design a feedback amplifier to supply a current to an led-

Design a feedback amplifier to supply a current to an LED. Use the configuration shown in given Figure where R_L is replaced by the LED.

(a) Assuming an ideal op-amp is available, design the circuit such that the diode current is I_o = 3 × 10^-3 V_i where V_i is in the range 0 to 5 V.

(b) If V_i = 5 V, what is the error in diode current if the op-amp has a finite gain of A_g = 10³ mA/V and h_{F E} = 80?
