Repeat Problem 4.29 assuming that the values of I_S, R₂, and R₁are nominal but that R₃is 1 percent low. Assume V_BE(on)= 0.6 V.

Data from Prob. 4.29:

A band-gap reference like that of Fig. 4.47 is designed to have nominally zero TC_F at 25°C. Due to process variations, the saturation current I_S of the transistors is actually twice the nominal value. Assume V_OS = 0. What is dV_OUT/dT at 25 °C? Neglect base currents.
