Abstract

The invention relates to a wide-stop-band noise suppression structure applied to a power distribution network in system-in-package and an intelligent optimization design method thereof. Compared withthe prior art, the defects that the noise suppression structure is low in efficiency, long in design period and difficult to optimize the design are overcome. According to the invention, a rectangulararea is divided on a device bearing copper plate; wherein the four sides of the rectangular area are composed of 72 rectangular blocks, the areas of the 72 rectangular blocks are the same, the transverse side of the rectangular area is formed by 20 rectangular blocks which are regularly arranged in two rows, the vertical side of the rectangular area is formed by 16 rectangular blocks which are regularly arranged in two columns, and a plurality of rectangular blocks are etched into a hollow structure. The shape of the electromagnetic band gap structure is designed on the power layer of the power distribution network, so that the noise suppression low-frequency cut-off frequency is reduced, and the noise suppression frequency bandwidth range is increased; the size of the distribution network is automatically optimized through an automatic optimization method, and the noise suppression depth is increased.

Description

technical field [0001] The invention relates to the technical field of power distribution network in system-level packaging, and specifically relates to a wide stopband noise suppression structure and an intelligent optimization design method applied to the power distribution network in system-level packaging. Background technique [0002] With the development of electronic systems towards high speed, high power consumption, high density, low voltage and high current, in future hybrid circuit systems, high-speed digital processors, memories, radio frequency (RF) / analog circuits, sensors, Integration of multi-functional devices such as micro-electro-mechanical systems (MEMS), optoelectronic devices, etc. This kind of micro-system integration also requires communication and computing capabilities. System-in-package (SOP) technology provides the most effective solution for package-chip co-design, and has become one of the trends in the development of microelectronics technology...
