Abstract
A differential voltage interconnect (W101a) electrically connects the gate electrode of a transistor to be used among differential transistors (T101a, T101a, . . . ) to an input node receiving an input voltage (Vinn), and a differential voltage interconnect (W101b) electrically connects the gate electrode of a transistor to be used among differential transistors (T101b, T101b, . . . ) to an input node receiving an input voltage (Vinp). A bias voltage interconnect (W102) electrically connects the gate electrode of a transistor to be used among current source transistors (T102, T102, . . . ) to a bias node receiving a bias voltage (VBN), and a bias voltage interconnect (W103) electrically connects the gate electrodes of transistors to be used among load transistors (T103a, T103a, . . . , T103b, T103b, . . . ) to a bias node receiving a bias voltage (VBP).
