Abstract
An ultra-low-power common-gate low noise amplifier (CG-LNA) for 2.4 GHz wireless sensor network (WSN) applications is proposed in this letter. The current-reuse and active gm-boosting techniques are utilized. The analysis, design method and measurement results are shown. An implemented prototype using 0.18 μm CMOS technology is evaluated using on-wafer probing. Measurements also show a gain of 14.7 dB and an IIP3 of 2 dBm at 2.44 GHz. The measured noise figure is 4.8 dB at 2.44 GHz. S11 is below -18 dB from 2-3 GHz. The proposed LNA consumes 0.58 mW from 1.8 V dc supply.
