Abstract
To provide a power supply noise reduction circuit and a power supply noise reduction method that do not require circuit elements to be increased in size and do not cause voltage drop in a power supply voltage. A power supply noise reduction circuitthat reduces noise included in a constant voltage output that is output from a power supplyto a load includes a first resistorthat is inserted into a power supply line Lextending from the power supplyto the load, a filterthat is coupled to a load terminal of the first resistorand outputs a first voltage that is obtained by reducing the noise from the constant voltage output, and a unity gain amplifierthat drives the first voltage output from the filterand outputs the driven first voltage to the load terminal of the first resistor
