Abstract
A reference voltage generation circuit of the present invention includes: a band gap reference-type current generation circuit for controlling each of currents flowing through a first current path and a second current path, which are extending from a first node to a second node, to be a predetermined reference current, by utilizing a voltage difference occurring between a pair of transistors or diodes; and a resistive load circuit provided between the second node and a third node.
