“…The resonant frequencies can be estimated by the equations (4) and (5). EM simulations or the circuit-based solution [16] can be used to simulate the characteristics of the input decoupling network more accurately. • Metal plate in the second layer which serves as an image plane should be designed the largest possible to maximize its effectiveness in reducing the radiated fields.…”

Radiation characteristics of an input decoupling network for switching DC-DC converters are analyzed by a set of electromagnetic (EM) simulations. Input decoupling network is a part of a DC-DC converter with a dominant contribution to its radiated emissions. The impact of geometrical parameters of an input decoupling network such as the dimensions of metal plates on a printed circuit board (PCB), thickness of a PCB, number of layers, number of vias and radius of vias on the maximum radiated fields is analyzed. Design guidelines for minimizing radiated emissions of an input decoupling network for switching DC-DC converters are summarized.Index Terms-electromagnetic (EM) interference, electromagnetic (EM) simulations, printed circuit board (PCB), radiated emissions, switching-mode power supply (SMPS).
