Capacitor values and quantities are calculated using time and frequency domain techniques in this article, where the authors propose a method for decoupling capacitors to reduce EMC/EMI radiated noise.
Abstract
CMOS circuits on printed circuit boards with continuous power planes require decoupling capacitors to keep power supply within specification, provide signal integrity and reduce EMC/EMI radiated noise. Capacitor values and quantities are calculated using time and frequency domain techniques.
