In the voltage reference circuit shown in the figure, the op-amp is ideal and the transistors Q₁, Q₂,...,Q₃₂ are identical in all respects and have infinitely large values of common-emitter current gain (β). The collector current (I_C) of the transistors is related to their base-emitter voltage (V_BE) by the relation I_C=I_Sexp(V_BE/V_T). Where I_S is the saturation current. Assume that the voltage V_p shown in the figure is 0.7 V and the thermal voltage V_T=26 mV. The output voltage Vout (in volts) is
