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

Abstract

Abstract-In this paper, a new method is proposed to calculate the simultaneous switching noise (SSN) in order to reduce the complexity of SSN circuit models and computational burden, which is based on the rational function (RF) in time domain. The time-domain impedance function of a power delivery network (PDN) is calculated by approximating the impedance frequency response of a PDN with a rational function, and the SSN is calculated based on switching current characteristics. It is also found that the SSN can be suppressed through adjusting the period of time-domain impedance function and switching current. Compared with the simulated results and measured results, the performance of the new method for calculating and suppressing the SSN is verified, and the simulation time of SSN is reduced effectively.

These parameters were estimated from the physical size of the BCI probe.…”

“…The main problem is the lack of reliable and convenient methods for analyzing and predicting PCB radiation. Until now, therefore, methods of diagnosing and solving problems of PCB radiated emission rely mostly on empirical experiences [1][2][3]. The difficulty in methods of predicting PCB radiated emission by simulation is the combination of circuit and electromagnetic models of practical interactions between integrated circuits and PCB traces [4].…”

“…The transient characteristics of the SSN and switching current are not considered in the target impedance method, and the studies in [25][26][27][28][29] have shown that frequency-domain analysis is not accurate enough at the high-frequency domain and analysis in time domain is required. The PDN circuit system can be simplified to a single resonance circuit model, as shown in Fig.…”
