We report a noise mapping strategy for the reliable identification and analysis of noise sources in molecular wire junctions. Here, different molecular wires were patterned on a gold substrate, and the current-noise map on the pattern was measured and analyzed, enabling the quantitative study of noise sources in the patterned molecular wires. The frequency spectra of the noise from the molecula...

Measurements in large scale SSF bioreactors are contaminated with various kinds of disturbances, such as high, medium and low frequency noise, outliers and missing values. These make the operation of many control systems for SSF bioreactors unreliable and ineffective. In addition, it is difficult, time consuming and expensive to assess new control strategies in real time experiments. Alternativ...

Frequency and timing of digital clocks, digital switching activities, and number of transistors in digital blocks are the key behavior-level parameters to model switching noise generated by complicated digital systems. In this paper, a Digital Noise Emulator (DNE) is implemented on a test chip to study how these parameters impact the performance of a ring-typed-VCO-based PLL. In addition, the p...

This paper presents the modeling and simulation of simultaneous switching noise (SSN) in on-chip power distribution networks (PDN). The circuit model of power buses over lossy silicon substrate is extracted as frequency dependent RLGC elements. The coupling between conductors on adjacent layers is represented as coupling capacitors. Accurate analytical formulae are derived to extract the RLGC t...

This paper summarizes the objectives and some early results of the ESPRIT project 29260 BANDIT. It is a 3 year project that started in September 1998. Coordinating partner is IMEC and the other partners are K.U.Leuven and Ericsson Radio Systems (ERA). The goal of BANDIT is to develop a general design and test methodology for embedding high-speed analog/digital converters (ADCs) on large digital...

This work is aimed to evaluate the role of nanoclay in the protective performance of an eco-friendly silane sol-gel layer applied on mild steel substrate in 0.1M sodium chloride solution. At the first step, the effect of pH of the silane solution, consisting of a mixture of γ-glycidoxypropiltrimethoxysilane and methyltriethoxysilane and tetraethoxysilane, on the coating performance was evaluate...

This paper presents an efficient modeling method, based on the microstrip lines theory, for the coupling between a substrate backplane and a device contact. We derive simple closed-form formulas for rapid extraction of substrate parasitic. We use these formulas to model spiral inductors as important substrate-noise sources in mixed-signal systems. The proposed model is verified for the frequenc...

The paper deals with the electromagnetic emissions of smart power System-on-Chips (SoCs). The propagation of core-logic switching noise through the silicon substrate and through the package lead-frame is investigated and the effectiveness of three different substrate grounding solutions to attenuate conducted emission is proved by means of computer analyses and experimental tests.
