A high-dynamic range ROIC for SLS and other IR focal planes
TL;DR: By using a novel serpentine readout sequence, this work has reduced the temporal bandwidth and enabled application of SDM technology for high dynamic range Focal Plane Arrays (FPA) and reconfigurable on-the-fly for a power vs. Signal to Noise plus Distortion Ratio (SNDR) tradeoff without “binning” or reducing the pixel pitch.
Grid Current Control for Active-Front-End Electric Propulsion Systems in AC Ship Microgrids
TL;DR: In this paper , a finite control set (FCS) current controller for grid-tied converters is proposed to meet the characteristics of ac ship microgrids in all-electric ships (AESs).

A higher order topology for interpolative modulators for oversampling A/D converters
TL;DR: Higher order modulators are shown not only to greatly reduce oversampling requirements for high-resolution conversion applications, but also to randomize the quantization noise, avoiding the need for dithering.

Decimation for Sigma Delta Modulation
TL;DR: It is shown that digital filters comprising cascades of integrate-and-dump functions can match the structure of the noise from sigma delta modulation to provide decimation with negligible loss of signal-to-noise ratio.

An analysis of nonlinear behavior in delta - sigma modulators
Sasan H. Ardalan,J.J. Paulos +1 more
TL;DR: This paper introduces a new method of analysis for deltasigma modulators based on modeling the nonlinear quantizer with a linearized gain, obtained by minimizing a mean-square-error criterion, followed by an additive noise source representing distortion components.

The Structure of Quantization Noise from Sigma-Delta Modulation
James C. Candy,O. Benjamin +1 more
TL;DR: Simple algebraic expressions for this modulation noise and its spectrum in terms of the input amplitude are derived and can be useful for designing oversampled analog to digital converters that use sigma-delta modulation for the primary conversion.

A fourth-order bandpass sigma-delta modulator
TL;DR: The modulator of a bandpass analog/digital (A/D) converter, with 63 dB signal/noise for broadcast AM bandwidth signals centered at 455 kHz, has been implemented by modifying a commercial digital-audio sigma-delta ( Sigma Delta ) converter.
