Abstract

An EMC macro-model of a 16-bit microcontroller with multiple-power-supply pins has been proposed for estimating the conducted EMI from a power-supply network. The macro-model, called the linear equivalent circuit and current sources (LECCS) model, is composed of multiple circuit blocks and multiple current sources corresponding to the composition of the chip circuits in the microcontroller, i.e., a current source for a circuit block. A current source statistically expresses the total RF current occurring in the corresponding circuit block. We confirmed that the proposed model could correctly estimate the RF power-supply currents under different decoupling conditions up to 300 MHz. We also found that a linear circuit of the regulator between the I/O and core circuit blocks could express the RF coupling between the two blocks.
