ABSTRACT:
Provided is an intermediate potential generation circuit with a lower power supply potential. The intermediate potential generation circuit includes: a current mirror circuit including a first transistor and a second transistor each having a source input with a power supply potential; a current source circuit including a third transistor having a drain connected to a drain of the first transistor; a grounded source amplifier circuit including a fourth transistor having a gate input with the intermediate potential, and a drain connected to a drain of the second transistor; a parallel connection circuit including a fifth transistor connected in parallel with the first transistor, and a sixth transistor connected in parallel with the second transistor; and a source follower circuit including a seventh transistor and an eighth transistor having gates that are connected in common to each other, and connected with the drains of the second transistor and the sixth transistor.
