1. An input circuit for transmitting a signal between semiconductor devices with an input stage and an output stage, said input circuit comprising:

  • a threshold value detecting means to detect a threshold value of said output stage; and

    a feedback amplifier that compares the threshold value and an amplitude center level of a signal fed from said input stage to said output stage such that said amplitude center level voltage can be made equal to said threshold value detected by said threshold value detecting means.
