Method of terminating bus, bus termination resistor, and wiring substrate having terminated buses and method of its manufacture

摘要

A terminal resistor is provided at the end of a bus formed on a wiring substrate. An insulator having a large dielectric loss angle is provided in the vicinity of the terminal resistor to absorb high frequency electromagnetic waves in the vicinity. This arrangement permits successful transmission of digital signals in the GHz region using a conventional terminal resistor.
