A CMOS low noise amplifier at 2.4 GHz with active inductor load

A two stage cascode CMOS low noise amplifier (LNA) with an active inductor load is presented. On-chip active inductors require 90% less silicon area at a higher quality-factor. Comparison of measurement and simulation of an active inductor shows the high quality factor. Simulations of the low noise amplifier show the advantages of active inductors with similar performance, even with regard to the noise figure. The simulated gain and noise figure are 19 dB and 2 dB respectively.
