Abstract
A reference voltage generation circuit includes a first current mirror including first through third transistors with the second transistor on a reference side thereof, a second current mirror including fourth and fifth transistors connected in series with the first and the second transistors, respectively, and a voltage control block for controlling the source-drain voltages the transistors on the output side of the first current mirror. The voltage control block includes a first control block having a configuration similar to the first current mirror, and a second control block having a configuration similar to the second current mirror, both of which are connected between the first current mirror and the second current mirror, with corresponding transistors connected in series. A stable output voltage can be obtained irrespective of variations in the potential of the voltage source for the reference voltage generation circuit.
