A bandgap reference circuit topology has been developed.Using high-order curvature compensation technique,the temperature performance of the voltage reference has been enhanced by offsetting the negative temperature dependence of the logarithmic term in Vbe(T) with a positive term.Hspice simulation shows that the temperature coefficient is 10 ppm/℃.
