ABSTRACT:
Provided is a semiconductor integrated circuit including: an output circuit connected between a power supply (VDD0) and a ground (GND0), having an input connected to an input terminal, and having an output connected to an output terminal; and a power-supply-noise cancelling circuit connected between the input terminal and the output terminal to generate a current that cancels a current flowing from the power supply (VDD0) to the output terminal or a current flowing from the output terminal to the ground (GND0), based on a potential difference between the input terminal and the output terminal.
