Abstract
A polysilicon resistor is added between a source (ground or power) of an EMI core circuitry and a source of the EMI peripheral circuitry. In this way, the electromagnetic interference of an integrated circuit is reduced. The added polysilicon resistor reduces the di/dt of the current passing between the power and the ground of the EMI core circuitry so that the EMI is reduced.
