A classical CMOS regulated cascode active inductor RFIC designed by de-embedding technique approach

The advent of modern communication systems has made the study of RF integrated circuits an attractive issue. However, the limitation of the passive integrated inductors is still a huge limitation. Integrated inductors take significant chip area, have low inductance values and unsatisfactory quality factors (Q). As a solution, active inductors have been proposed. In this work the de-embedding technique is applied in the design of an integrated active inductor in CMOS technology for RF systems, in order to analyze and eliminate all external influences to the designed element.
