Abstract:
Various embodiments of the present invention relate to a reference voltage generator circuit. Specifically, the circuit may for example comprise: a mirror constant current source having a first branch and a second branch, wherein a first current on the first branch is proportional to a second current on the second branch; wherein the first branch has a first resistive element, and the second branch has two second resistive elements connected in series; and a power supply terminal located between said two second resistive elements on the second branch. A high-precision reference voltage relative to the voltage source can be provided at the power supply terminal by using the circuit provided by various embodiments of the present invention.
