WSi2 - GPSOI Substrates and Their Influence on
Cross-talk Suppression and Inductance
(by Dr. Paul Baine)
The Performance of RF analogue circuits in Integrated Mixed signal Telecoms IC’s can be compromised by cross-talk through the silicon substrate from adjacent digital circuits. This becomes more severe as the frequency is increased especially in SOI. A solution to this problem is to integrate a WSi2 ground plane into the SOI structure in order to reduce the cross-talk.
