Abstract

The invention provides a power supply allocation network based on plane S-type bridge electromagnetic band-gap structures. The power supply allocation network comprises a power supply plane, a dielectric substrate and a ground plane. The dielectric substrate covers the ground plane. The power supply plane is arranged on the dielectric substrate. Plane S-type bridge electromagnetic band-gap structure units periodically extend on a two-dimensional plane on which the power supply plane is positioned so that a matrix is formed. Each plane S-type bridge electromagnetic band-gap structure unit comprises a patch and four half S-type bridges. The connecting parts of the patch and the half S-type bridges are provided with slots so that slits are formed. The four half S-type bridges are respectively provided with four lead-out ends which are arranged at the upper, lower, left and right parts of the whole structure unit. The four lead-out ends of one plane S-type bridge electromagnetic band-gap structure unit are respectively connected with one of the lead-out ends of the upper, lower, left and right adjacent plane S-type bridge electromagnetic band-gap structure units so that a plane S-type bridge is formed. The power supply allocation network based on the plane S-type bridge electromagnetic band-gap structures has great simultaneous switching noise suppression capacity within wide frequency range and has great power supply integrity.

Description

technical field [0001] The invention relates to the technical fields of high-speed circuits, electromagnetic fields and microwaves, in particular to a power distribution network based on a planar S-bridge electromagnetic bandgap structure, especially a power distribution for solving the problem of synchronous switching noise suppression of modern high-speed digital circuits The internet. Background technique [0002] With the development of modern digital communication systems, the integration of the system is constantly improving. At the same time, in order to meet the requirements of high speed and low power consumption of the system, the edge of the high-speed clock signal is constantly becoming steeper, and the signal voltage is constantly decreasing. The simultaneous switching noise (Simultaneous Switching Noise, SSN) generated by a large number of high-speed switching devices in the working process of the high-speed circuit system, also known as the ground bounce noise...
