Quick Power Supply Noise Estimation Using Hierarchically Derived Transfer Functions
نویسندگان
چکیده
The Analysis of power supply noise on VLSI chips is becoming important. In this paper we propose a new methodology for the estimation of power supply noise, caused by digital switching activity. Using transfer function calculated hierarchically from Fmatrices, this method makes it possible with dramatically reduced computational cost to estimate power supply noise at all the nodes in power supply lines, which is linear to node number. The present method is shown efficient and valid enough compared with HSPICE simulation.

Analysis of DLL Jitter Affected by Power Supply Noise on Power Distribution Network
In this paper, we analyze a noise-to-jitter transfer function on DLL (Delay Locked Loop) considering power supply noise effects on PDN (Power Distribution Network). Noise-tojitter transfer function of DLL circuit can be estimated by using single-tone power supply noise analysis. Noise transfer function through the PDN can be obtained from transfer impedance of hierarchical PDN using TLM (Transm...
متن کاملVector generation for power supply noise estimation and verification of deep submicron designs
This paper presents new techniques for generating a small set of patterns for power network simulation to estimate the maximum power supply noise of the chip, as well as to identify cells/blocks for which the power supply noise at their dd ports exceeds a specified threshold. We first present an efficient, celllevel simulator for estimating power supply noise of any given vectors. Based on this...
متن کاملEstimation of harmonic interference parameters of surface-NMR signal using an adaptive method and residual signal power
Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...

Estimating the fundamental frequency and harmonic parameters is basic for signal modeling in a power supply system. This paper presents a complexity-reduced algorithm for signal reconstruction in the time domain from irregularly spaced sampling values. Differing from the existing parameter estimation algorithms, either in power quality monitoring or in harmonic compensation, the proposed algori...
متن کاملEstimation of Source Location Using Curvature Analysis
A quadratic surface can be fitted to potential-field data within 3×3 windows, which allow us to calculate curvature attributes from its coefficients. Phillips (2007) derived an equation depending on the most negative curvature to obtain the depth and structural index of isolated sources from peak values of special functions. They divided the special functions into two categories: Model-specific...
