摘要： An insulative magnetic layer is disposed between a power source conductor layer and a ground conductor layer of a printed-wiring board. Two pieces of conductors are formed by cutting out a part of the power source conductor layer. Another two pieces of conductors are formed by cutting out a part of the ground conductor layer. The former conductors and the latter conductors are connected by five viaholes. A spiral coil inductor of a spiral form is formed in this way. This inductor has the strengthened inductance owing to the insulative magnetic layer provided therein.

摘要： Transmission line type components (1, 1′), which form coaxial lines having a very low characteristic impedance by coaxially installing a cylindrical outer conductor made of a conductive material being larger in diameter than an inner conductor so as to cover via a high dielectric insulating material the surface of an inner conductor made of a conductive material, are inserted in series between a power supply line (8) and a ground line (9) connected with a dc source on a printed circuit board and an I.SI (6) power supply port, whereby almost the entire high-frequency power supply current generated from the I.SI (6) is reflected off the I.SI (6) power supply port, and part of the high-frequency power supply current intruding into the components (1, 1′) is consumed and does not reach the external power supply line (8).

摘要： There is provided a multi-layered printed wiring board including a power supply layer, a ground layer, a signal layer, and insulators sandwiched between those layers. The power supply layer is provided with a circuit in the form of wirings for imparting impedance thereto. For instance, the power supply layer may be formed to include main wirings for distributing a dc current entirely to the printed wiring board with a dc voltage drop being depressed, and branch wirings for enhancing high frequency impedance to isolate circuits in terms of high frequency, which circuits are mounted on the multi-layered printed wiring board and operated independently with each other. The invention makes it possible to provide a relatively great inductance to thereby decrease high frequency power supply current which is generated on IC/LSI operation and is to flow into decoupling capacitors. In addition, in accordance with the present invention, it is possible to identify a route through which a current runs into the power supply layer to thereby provide an optimal decoupling capacitor to every IC/LSI as a source of high frequency power supply current.
