Abstract
A reference voltage generation circuit may include: a first reference current path formed through a first node and a first transistor; a second reference current path formed through a second node and a second transistor; a first feedback loop configured to feed a first current back to the first and second reference current paths such that voltage levels of the first and second nodes are kept the same; and a second feedback loop configured to control the currents flowing through the first and second transistors according to a second current.
