Simultaneous switching noise suppression for high speed systems using embedded decoupling

A New Efficient Method for Calculation and Suppression of Simultaneous Switching Noise With the Time-Domain Impedance Function for High-Speed Circuit Design

“…So the SSN of the i-th port could be calculated as (19) where i j (t) is the switching current of the j-th port, z ij (t) is the inverse Laplace transformation of Z ij (s), so the SSN of a multi-port PDN could also be calculated with the proposed method.…”

“…Many studies have focused on the suppression of noise transmission, such as embedded capacitors [18,19] are commonly used in the power bus to mitigate the high frequency noise due to their lower inductance. Power islands [20,21] are used to isolate devices that put noise on a power bus from devices that may be susceptible to power bus noise.…”

“…Indeed, the elimination of SSN in multilayer PCB is a critical task in the phase of the design to assure signal integrity. Several methods have been used to reduce the harmful effects of noise transmission, such as integrated capacitors, which are used at high frequencies because of their low inductance [8,9]. Another method to remove noise is the introduction of lossy components serving for the elimination of resonance based on the increase of the component loss [10].…”

Estimation Method for Simultaneous Switching Noise in Power Delivery Network for High-Speed Digital System Design

“…Decoupling capacitors are used to realize low impedance in frequency domain and the number of capacitors on a PC should be minimized from a cost point of view. Hence, the proper number of decoupling capacitors, and the proper value of the decoupling capacitors should be chosen carefully [15,16]. Electromagnetic band-gap (EBG) structures are proposed to suppress the SSN in GHz range because of their highimpedance planes, however signal integrity is degenerated by periodic EBG structures, because the periodic structures on the power plane seriously affect the return path, and the applications of EBG in the package and chip need to be studied [17][18][19][20].…”
