Well, the bandgap tempco voltage consists of two parts, Voltage due to the PTAT current over a resistor and -ve coefficient voltage, VBE. The PTAT Current is due to the ΔVBE/R of the input loop. Hence the final voltage will be responding positively at lower temperatures and to the VBE at higher temperatures. Hence you get a convex shape.
