Fom said:Run DC analysis with temperature as sweeping parameter.
Using calculator select VS of bandgap voltage. Then select DERIV Special function of calculator and click plot. You will get TC. If you prefer PPM multiply it by 1000000.
After following the above instructions, I got another graph plotted which is the derivative of the first. So how to get the TC in ppm/oC?
Sincere Thanks

The relative temperature dependence of your ref. voltage (in \[\ \frac{ppm}{°C}\]) will change over the temperature range. Which value you should take depends on your specification needs: you could specify several \[\ \frac{ppm}{°C}\] values for their corresponding temperature points, or you could specify min. & max values for a specified temperature range, or a mean value for such a range ± its max. deviations, e.g. for the application temperature range.So which point should I take to be the TC?
