Abstract
A reference voltage generator circuit includes: a first transistor and a second transistor, wherein the first transistor and the second transistor are coupled with each other and are located on a substrate, wherein the first transistor has a first conduction threshold voltage and a first rated voltage, wherein the second transistor has a second conduction threshold voltage and a second rated voltage, wherein the first rated voltage is higher than the second rated voltage; wherein the reference voltage generator circuit is configured to generate a bandgap reference voltage with temperature compensation according to a difference between the first conduction threshold voltage and the second conduction threshold voltage.
