    Abstract: A voltage generation circuit includes a current generation circuit, a slope trimming circuit and an offset trimming circuit. The current generation circuit is connected between an input voltage node and an output node that outputs a complementary to absolute temperature (CTAT) output voltage that decreases as an operation temperature increases. The current generation circuit generates a reference current flowing through the output node, the reference current having a constant magnitude regardless of the operation temperature. The slope trimming circuit is connected between the output node and an intermediate node. The slope trimming circuit adjusts a slope of the CTAT output voltage based on a first trimming code. The offset trimming circuit is connected between the intermediate node and a ground voltage node. The offset trimming circuit configured to adjust an offset voltage of the CTAT output voltage based on a second trimming code.
