Abstract:
1. A circuit comprising: a plurality of source followers, each source follower including a first transistor and a second transistor; a first power supply line electrically connected to a gate electrode of the second transistor in each source follower; a second power supply line electrically connected to a source electrode of the second transistor in each source follower; a third power supply line; and a plurality of constant current sources, each constant current source disposed between the first power supply line and the third power supply line and electrically connected to the first power supply line and the third power supply line; wherein a source electrode of the first transistor is electrically connected to a drain electrode of the second transistor; wherein an output potential of each source follower is corrected by correcting a potential of the first power supply line by the constant current source and the third power supply line.
