Semiconductor device capable of adjusting input resistance without changing input terminal capacitance

摘要

A semiconductor device is capable of adjusting an input resistance without changing an input terminal capacitance. The capacitance formed by a capacitive wiring and a comb-shaped wiring can be adjusted by changing the length of the capacitive wiring. The resistance between the capacitive wiring and the ground potential can be adjusted by changing the positions of contacts which interconnect the capacitive wiring and a resistive wiring. Since the resistance can be adjusted simply by changing the connections of the contacts, only the input resistance can be adjusted without changing the input terminal capacitance.
