Abstract :
Overall EMI level of keyboard controlled IC has been improved to the level of satisfaction in the specification, which is believed to be the first time in the chip level. The ground-to-power line decoupling capacitance, the output RC filtering (or capacitance alone), and the formation of microstrip line have shown to be possible solutions for suppressing EMI characteristics in the chip level. The output RC filtering has resulted to satisfy the specification of FCC the most. The electric field peak and average value was improved to 8.8 dB and 3.1 dB respectively
