An Overview of the Research on CMOS Bandgap Reference Sources
Zhihua Wang · 2008
Bandgap reference source is an important unit in integrated circuits,which supplied reference voltage or current independent of temperature and supply voltage.The principle of CMOS bandgap reference source was described,and the design challenge was pointed out.Finally,CMOS bandgap reference sources with low supply voltage,low power,high precision and high PSRR were analyzed,respectively.
