摘要
This paper presents amethodology dedicated to modeling and simulation of low-dropout (LDO) voltage regulator susceptibility to conducted electromagnetic interference (EMI). A test chip with a simple LDO structure was designed for EMC test and analysis. A transistor-level model, validated by functional tests, Z-parameter characterization and direct power injection (DPI) measurements, is used to predict the immunity of the LDO regulator. Different levels of model extraction reveal the weight contributions of subcircuits and parasitic elements on immunity issues. The DPI measurement results show a good fit with model prediction up to 1 GHz.
