A Comprehensive Tool for Modeling CMOS Image-Sensor-Noise Performance

Abstract: Accurate modeling of image noise is important in understanding the relative contributions of multiple-noise mechanisms in the sensing, readout, and reconstruction phases of image formation. There is a lack of high-level image-sensor system modeling tools that enable engineers to see realistic visual effects of noise and change-specific design or process parameters to quickly see the resulting effects on image quality. This paper reports a comprehensive tool, written in MATLAB, for modeling noise in CMOS image sensors and showing the effect in images. The tool uses accepted theoretical/empirical noise models with parameters from measured process-data distributions. Output images from the tool are used to demonstrate the effectiveness of this approach in determining the effects of various noise sources on image quality

A metal-oxide-semiconductor varactor

Abstract: CMOS technology scaling opens up the possibility of designing variable capacitors based on a metal oxide semiconductor structure with improved tuning range and quality factor. This is due to an increase in the oxide capacitance and a reduction in the parasitic resistance. A prototype metal-oxide-semiconductor (MOS) variable capacitor of 3.1 pF nominal value has been realized in a 0.35-/spl mu/m standard CMOS process. A factor two capacitance change has been achieved for a 2-V variation of the controlling voltage. The varactor Q ranges from 17 to 35, at 1.8 GHz.

Media player for distribution of music samples

Abstract: A method and apparatus of music distribution from a media player. A media player is provided with a “send to friend” icon. In one embodiment, when the icon is selected, a clipping of the currently playing music selection is taken from a predetermined location in the music selection and compressed using a fidelity reducing compression technique to produce a sample of the current selection suitable for distribution. The compressed clipping is sent to a selected recipient or recipients by email in the background while the music selection continues to play. The recipient(s) can be either a default recipient(s) or a recipient(s) selected from a list as in an address book application.

Evolution of materials technology for stacked-capacitors in 65 nm embedded-DRAM

Abstract: The architecture, materials choice and process technology for stacked-capacitors in embedded-DRAM applications are a crucial concern for each new technology node. An overview of the evolution of capacitor technology is presented from the early days of planar PIS (poly/insulator/silicon) capacitors to the MIM (metal/insulator/metal) capacitors used for todays 65 nm technology node. In comparing Ta2O5, HfO2 and Al2O3 as high-k dielectric for use in 65 nm eDRAM technology, Al2O3 is found to give a good compromise between capacitor performance and manufacturability. The use of atomic layer deposition (ALD) is identified to be an enabling technology for both high-k dielectrics and capacitor electrodes. � 2005 Elsevier Ltd. All rights reserved.
