Digital processors are typically implemented in the latest CMOS process to take advantage of the increased density and performance afforded by CMOS scaling. Integration of traditional RF circuits, however, requires accurate RF and passive models that typically lag behind digital transistor models by several quarters. This makes RF integration the limiting factor for time-to-market for the whole SoC, or results in sub-optimal multiple-chip solutions. Furthermore, traditional RF circuits do not benefit from scaling as digital circuits do, e.g. due to extensive use of inductors, the
