Abstract

Analysis of electromagnetic noise mitigation in a mixed signal board consisting of analog to digital convertor (ADC) and low noise amplifier (LNA) is presented. A new approach of mitigating the electromagnetic noise is proposed in the form of complementary split ring resonator (CSRR) loaded right handed (RH) transmission line as an alternative to EBG loaded large power planes. To analyze the effect of electromagnetic noise in mixed signal board, noise coupling power and noise figure at the output of LNA were measured for various periodic configurations (RH transmission line, alternating impedance electromagnetic bandgap (AIEBG), and CSRR loaded transmission line). The noise figure at the output of LNA is 11.5 dB, 2.9dB and 2.7 dB for RH transmission line, AIEBG based power plane and CSRR loaded RH transmission line respectively.
