仿真10ppm容易，流片出来是10ppm的难度大

简单温度补偿电路，在.18或.35里面，做得效果一般
复杂电路的话....就不知道了，没做过

use second order curvature correction and maybe trim resistor to get 10ppm

You can also try malcovati;s architecture.But be careful about offset in this architecture.Use high gain opamp in the BG.

thanks for sharing! but I really wonder about second order compensated!
