Description: At the 90-nm node, silicon technologies have reached a point where the transistor fT and f MAX simultaneously exceed 150 GHz, with a 1.2 V supply. With low fabrication costs for high volumes of circuits, RF-CMOS technologies are ideally suited to realize exciting new high bandwidth consumer products that operate in the mm-wave regime. Before this can happen, models of both active and passive devices will require a high degree of accuracy from DC, all the way up to mm-wave frequencies.This thesis presents new techniques that help leverage the power of measurements to characterize and model devices of nano-CMOS technologies well into the mm-wave regime. In particular, two new de-embedding techniques are devised in order to improve measurement accuracy, and reduce wafer area consumption. Moreover, the measured characteristics of various microstrip lines, varactors, and n-MOSFETs fabricated in a 90-nm RF-CMOS technology are analyzed in order to identify optimal geometries for high frequency design. An extraction methodology for a scalable physical model of accumulation-mode MOS varactors is also included.
