Fully-integrated amplifier feedback linearization design analysis

Abstract

In this paper, the design of a fully-integrated amplifier feedback linearization is presented. Simulation results have yielded a peak S21 power gain of 10.3 dB and a unity gain bandwidth of 16 GHz with better than −10 dB S11. The simulation results show a 7 dB IIP3 improvement and IM3 improvement of 18 dBc at output power of −10 dBm. Using derivative superposition improves the feedback amplifier broadband linearity and in turn improves its dynamic range. The proposed fully-integrated amplifier feedback linearization was designed using the 0.13μm CMOS technology.
