Improvement of Bandgap Reference Temperature Characteristic by Optimizing Model Parameters
Wenping Liu · Microelectronics & Computer · 2008
Based on the theory of GP model and Process Data,a method of optimizing the key temperature parameters such as XTB and XTI is discussed in this paper,and it's proved in a typical bandgap reference circuit with Hspice simulation which the temperature characteristic of bandgap reference can be improved ranging from-55℃ to 125℃.
