An accurate design of fully integrated 2.4GHz CMOS cascode LNA

摘要

This paper presents a full integrated 2.4GHz inductively degenerated cascode low noise amplifier (LNA) realized in a standard TSMC 0.25-/spl mu/m CMOS process. The source degenerated inductor has been design after the electromagnetic (EM) analysis using the calibrated substrate conditions. The measured performance of the proposed LNA shows the noise figure (NF) of 2.87 dB, the power gain of 13.29 dB, and the reverse isolation of -30.8 dB. High linearity design with the output 1 dB gain compression point (PldB) of 0 dBm, input third-order intercept point (IIP3) of 2.2 dBm, and the power consumption is only 11 mW while dissipating 5.5 mA from a 2 V supply. The overall measured results of the implemented LNA show good agreement with simulated results.
