Abstract
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.
