Abstract: A bandgap reference circuit includes a reference current generation circuit configured to output a bandgap reference current insensitive to a temperature change, by using a first voltage inversely proportional to temperature and a third voltage proportional to temperature. The third voltage is a difference between the first voltage and a second voltage. The bandgap reference circuit further includes a resistivity temperature coefficient cancellation circuit configured to remove a first current proportional to temperature from the bandgap reference current by using the third voltage, and a reference voltage generation circuit configured to output a bandgap reference voltage insensitive to a temperature change by using a second current inversely proportional to temperature and a first resistance proportional to temperature. The second current is generated by removing the first current from the bandgap reference current.
