Abstract:

The development and basic working theory of reference source are introduced.The bandgap circuit structure,which is a universal voltage reference source form,is discussed in detail.A circuit of bandgap based on Banba structure is designed,and the relationship between output voltage and temperature is analyzed.The design can provide reference voltage for serial voltage regulator circuits and A/D & D/A converters and serve as the stable voltage power supply or driving source of most sensors.

Key words: reference source;Banba;bandgap;output voltage
