Abstract
A semiconductor integrated circuit includes a macro connected between a first power supply line and a second power supply line to drive a load, and a power-supply-noise cancelling circuit connected between an input and an output of the macro to generate a current for canceling one of a current flowing from the first power supply line to the output of the macro and a current flowing from the output of the macro to the second power supply line, on the basis of a potential difference between the input and the output of the macro. The macro and the power-supply-noise cancelling circuit are mounted in a same chip.
