SEMICONDUCTOR INTEGRATED CIRCUIT HAVING DIFFERENTIAL AMPLIFIER AND METHOD OF ARRANGING THE SAME

摘要

A semiconductor integrated circuit comprises: a transistor region having a center line; a first block arranged in one side of the center line of the transistor region, and comprising a plurality of first and second groups each having a plurality of first and second segment transistors constituting first and second transistors of a differential amplifier; and a second block arranged in the other side of the center line, and having an arrangement corresponding to the arrangement of the first and second groups of the first block.

1. A semiconductor integrated circuit comprising:
a transistor region having a first center line to divide the transistor region into a first area and a second area; a plurality of first groups arranged in the first and second area of the transistor region; and a plurality of second groups arranged in the first and second area of the transistor region, wherein the first and second groups are arranged to have a folded symmetry with respect to the first center line of the transistor region, the plurality of the first groups and the plurality of the second groups include a plurality of first segment transistors constituting a first transistor to receive a first signal, and a plurality of second segment transistors constituting a second transistor to receive a second signal, and arrangements of the first and second segment transistors of the first groups are opposite to those of the second groups.
