a continuous time spl sigma spl delta modulator with reduced sensitivity to clock jitter through scr feedback
IEEE Transactions on Circuits and Systems, 2005Co-Authors: Maurits Ortmanns, Friedel Gerfers, Yiannos ManoliAbstract:This paper presents a means to overcome the high sensitivity of continuous-time sigma-delta (/spl Sigma//spl Delta/) modulators to clock jitter by using a modified switched-capacitor structure with Resistive Element in the continuous-time feedback digital-analog converter (DAC). The reduced sensitivity to jitter is both simulated and proven by measured results from two implemented third-order modulators. Additionally, the nonideal behavior is analyzed analytically and by simulations.

Overland flow to and through a segment of uniform resistance
Journal of Hydrology, 2002Co-Authors: Calvin Wyatt Rose, W. L. Hogarth, Hossein Ghadiri, Jean-yves Parlange, Augustine E.a. OkomAbstract:Recognising the utility of grass buffer strips in sediment retention, a fundamental hydraulic interpretation of flow through such strips is sought. In order to ensure reproducibility of results, a model porous Resistive Element consisting of beds of nails of various densities was used to simulate the hydraulic resistance offered by grass strips. In 14 experiments, the hydraulic consequences were measured for steady flow in a flume through nail beds of various densities at various flume slopes. A newly devised staining technique was used to measure the spatial variation in water depth to and through the Resistive Element. Provided nail density was not too low or slope too high, the maximum depth of water occurred as flow entered the nail bed. In such cases, momentum theory was able to provide a reasonably good prediction, both of the shape of the water profile within the nail bed, and of the slope and extent of the region of hydraulic adjustment formed upslope of the Resistive Element.Griffith Sciences, Griffith School of EnvironmentNo Full Tex

A Nano-Transistor Based on Gate-Induced Thermal Switching
International Journal of Theoretical and Applied Nanotechnology, 2012Co-Authors: J. Bürki, Charles A Stafford, Daniel L. SteinAbstract:A nanoscale device consisting of a metal nanowire, a dielectric, and a gate is proposed. A combination of quantum and thermal stochastic effects enables the device to have multiple functionalities, serving alternately as a transistor, a variable resistor, or a simple Resistive Element with changeable I-V characteristics. By manipulating the gate voltage, stochastic transitions between different conducting states of the nanowire can be induced, with a switching time as short as picoseconds. With an appropriate choice of dielectric, the transconductance of the device can significantly exceed the conductance quantum, a remarkable figure of merit for a device at this lengthscale.
