Abstract
A bandgap reference circuit generates a PTAT voltage and a CTAT voltage having a different temperature characteristic from the PTAT voltage and generates a reference voltage based on the PTAT voltage, the CTAT voltage, and a compensation voltage. The bandgap reference circuit generates a CTAT current having a different temperature characteristic from the PTAT voltage based on the CTAT voltage and determines the compensation voltage based on the CTAT current.
