Abstract

A 1.3GHz cascode low noise amplifier based on 0.25/spl mu/m CMOS technology has been successfully designed in this paper. From the aspect of noise optimization, gain and impedance match, the design methodology for LNA is analyzed in detail, the influence of capacitance C/sub gd/, C/spl I.bar/match/spl I.bar/in, and W/sub 2/ on LNA is also discussed, whose noise factor and S-parameter is simulated and tested by the ADS software. The result has argued that the good NF of 1.42dB, moderate gain of 13.687dB, acceptable S11 of -14.769dB, S22 of -14.530dB, S12 of -52.955dB are achieved under the frequency of 1.3GHz.
