Patent ID: 7961037

Claim:
An intermediate potential generation circuit, comprising: a reference potential generation circuit that generates a reference potential serving as a reference for an intermediate potential; 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 gate input with the reference potential, a source grounded, and 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, a source grounded, and a drain connected to a drain of the second transistor; a parallel connection circuit including a fifth transistor having a gate input with the intermediate potential, and a source and a drain respectively connected in common to a source and the drain of the first transistor, and a sixth transistor having a gate input with the intermediate potential, and a source and a drain respectively connected in common to a source and the drain of the second transistor; and a source follower circuit including a seventh transistor and an eighth transistor having opposite carrier structures of p-type and n-type, and gates that are connected in common to each other, and connected with the drains of the second transistor and the sixth transistor.
