Semiconductor device including input buffer circuit capable of amplifying input signal with low amplitude in high speed and under low current consumption

摘要

A semiconductor device is arranged by a push-pull circuit 1 for shifting a first center potential of an amplitude of an input signal to a second center potential, and for outputting first and seconc complimentary signals P1, P2 having said second center potential, and further a bipolar type differential amplifier 2 for receiving the first and second complementary signals as input signals thereof.
