Optimization of shield structures in analog integrated circuits

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.
