Modeling and Experimental Verification to Investigate the Effect of Power Supply Noise Imbalance on 900MHz Differential LNA
In this paper, the effect of power supply noise imbalance on 900 MHz differential low noise amplifier (LNA) output is investigated. Chip and package (PKG) power distribution network (PDN) are modeled with lumped components to estimate the power supply noise imbalance. Also an equivalent circuit of differential LNA is modeled to estimate the noise voltage at differential LNA output and verified through measurements. The results of this study reveal that the power supply noise imbalance is mainly caused by impedance resonances of PKG PDN and it directly coupled to the differential LNA output.
