Abstract
Official abstract text for this publication.
A novel and useful fabricated variable transmission line that is tuned digitally is presented. Digital tuning of the variable transmission line enables the compensation of process variation in both the active and passive devices of the RF design. Along with several embodiments of the variable transmission line, the present invention also provides a method of compact modeling of the variable transmission line. The variable transmission line structure and compact modeling enables circuit level simulation using a parametric device that in one embodiment can be included as an integral part of a silicon foundry design kit.
First claim
Opening claim text (preview).
What is claimed is: 1. A variable transmission line, comprising: a semiconductor substrate; a signal line; a first plurality of capacitor ports below said signal line, each capacitor port operative to be connected to either a bottom ground plane or a floating potential; one or more side shield wires to modify inductance of the signal line, wherein the first plurality of capacitor ports are not physically coupled to the one or more side shield wires such that each of capacita…
