Abstract
The effect of shield structures for local wirings of analog integrated circuits on crosstalk is determined by electromagnetic simulation. The crosstalk of parallel wirings is reduced to -70 dB by the shield above and between the wirings. The optimal shield structure and terminal-impedance dependence are determined by numerical analysis taking terminal impedance as well as wiring length and width into consideration.
