| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A deep n-well guard-ring, DNW-GR, provides effective isolation from substrate-coupled high frequency noises in combination with high-resistive p-type substrates. AC-measurements of S21 with port geometry and guard-ring structure dependencies are reported in a 0.25-$\mu$m CMOS standard mixed-signal technology with p-type substrates having the bulk resistivity from 10 $\Omega$cm to 3 k$\Omega$cm. It is shown that DNW-GR on a 1-k$\Omega$cm substrate gains 20dB improvement in isolation against 1GHz coupling, compared with a p+ guard-ring on a standard 10$\Omega$cm substrate. S21 simulations with substrate equivalent circuit models derived by way of F-matrix computation on test structures are in good agreement with measurements for a frequency range over 5GHz. The substrate models can compactly as well as precisely include layout-level isolation effects in circuit simulations for a mixed-signal/RF design. | |
