The Design of Bandgap Reference Based on Empyrean Aether Software

Abstract

A high-performance bandgap reference voltage source design method is proposed in this paper, according to the shortcomings of traditional bandgap reference voltage source. This method combined CSMC 0.35μm CMOS process with Aether software technology, enabling to improve the bandgap reference source op amp performance and take into account accuracy and stability of the system. From the experimental results: this bandgap reference voltage source output voltage has changed about 63 mV when the temperature varied from to , and the line regulator is 0.4mV/V when the power supply voltage varied from 3.2V to 3.3V. This system has advantages of high accuracy and good stability.
