Abstract

We demonstrate a proof of concept to implement carbon nanotubes (CNT) in radio frequency (RF) integrated circuits to achieve improved electromagnetic isolation. A densely packed CNT fence-wall was designed on a typical via-fenced guard structure, to create RF isolation between two transmission lines. Both simulations and measurements have shown to further reduce forward and backward coupling by 10 dB over current techniques in the 1-10 GHz range. Such CNT isolation scheme could be implemented in densely packed three-dimensional circuits and packages.
