Abstract
In an electronic device supplying a DC power to an LSI chip ( ), a noise filter ( ) of a distributed constant type, having an input port ( ) and an output port ( ), is mounted on a circuit board ( ). The noise filter ( ) reduces high-frequency noise incoming thereto and allows DC current to flow therethrough. The input port ( ) is connected to a DC power line ( ) and a ground conductor ( ) on the circuit board ( ). The output port ( ) is connected to a separate power conductor ( ) and a separate ground conductor ( ) which are connected to the LSI ( ) mounted on the circuit board ( ). In another embodiment, the LSI ( ) is mounted on a different circuit board ( ) to which the output port ( ) is connected through conductor pins ( ) standing on the circuit board ( ).
