Abstract
A power supply noise eliminating method eliminates power supply noise in a semiconductor integrated circuit having a plurality of first terminals coupled to a first power supply voltage and one or a plurality of second terminals coupled to a second power supply voltage which is different from the first power supply voltage. The power supply noise eliminating method includes the steps of (a) supplying the first power supply voltage to one of the first terminals, and (b) supplying the second power supply voltage to another one of the first terminals via an impedance circuit, thereby eliminating the power supply noise with respect to at least the first power supply voltage.
