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_S exp ((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=26mV.

The output voltage V_out (in Volts) is______
