Research on Design Method and Application of Bandgap Voltage Reference

Abstract. With the progress and development of modern science and technology, more and more fields are inseparable from analog IC, and the demand for analog IC is increasing. From aerospace to mobile phones and televisions, analog IC are an indispensable part of these fields. In analog IC, one of the most common core components is a voltage reference that outputs a stable voltage that is not affected by temperature. However, the working environment of the voltage source will be different in different fields, so the design of voltage reference that meets the needs of their respective fields is one of the key research topics today, but there is still a lack of comparison and summary of the advantages and disadvantages of the different structures of the voltage reference used in different fields. Therefore, the research theme of this paper is to introduce the structure of voltage reference used in different fields, and compare and analyze the advantages and disadvantages of different structures, and discuss the development direction of future voltage reference on this basis.
