Semiconductor integrated circuit
In an integrated circuit having a feedback amplifier circuit composed of the feedback which feedbacks a part of the output signal to the input side in the first stage, a semiconductor integrated circuit of the present invention can suppress the occurrence of the data signal distortion and the gain peaking of the frequency characteristic generated by inter-stage wiring between the first stage and the latter stage.A semiconductor integrated circuit of the present invention includes the first circuit and the second circuit having the first output connected to the first circuit, and the second output that is a signal similar to said first output is outputted from between said first circuit and said second circuit. In addition, a semiconductor integrated circuits of the present invention has the feature that the output impedance pulled out from between said first circuit and said second circuit, the input impedance of the circuit connected to the latter stage of said second circuit and the characteristic impedance of the wiring which connects said second output with a circuit connected to the latter stage of said second circuit are equal to each other.
