Band gap reference
I designed a Bandgap reference to have a Zero Temp co at Room temp (25 deg C). I get 1.2V at 25C, however, the plot of Vref and temp does not look correct. Also, i plotted d(vref)/dT, and at any temperature it does not cross 0.
I am attaching a copy of my schematic, plot o fVref Vs Temp and the temp co.
Can someone please help me in what is wrong with the circuit?
