Distortionless analog-to-digital conversion
Computer Standards & Interfaces, 1999Harmonic distortion is introduced by nonlinear flash analog-to-digital converters (ADCs) and even small-scale dithering does not reduce this unwanted effect. Large-scale dithering has been proposed to overcome this limitation. However, large-scale dithering is difficult to implement and, in addition, it severely reduces the ADC input dynamic range.

Stochastic-flash analog-to-digital conversion
IEEE Transactions on Instrumentation and Measurement, 1998Flash-type analog-to-digital converters (ADC's) presenting a nonlinear behavior, i.e., having nonequally spaced threshold levels, may introduce harmonic distortion that can be reduced by employing large-amplitude dither-based conversion techniques. However, large-scale dithering is difficult to implement and, in addition, severely reduces the ADC input

This chapter begins with a brief overview of analog-to-digital (A/D) conversion, wherein quantization error is considered for both Nyquist-rate and oversampling A/D converters. A subclass of oversampling converters based on noise-shaping topologies commonly referred to as sigma-delta (ΣΔ), or equivalently delta-sigma (ΔΣ), modulators are then examined.

Optical oversampled analog-to-digital conversion
Applied Optics, 1992Previously,1 we introduced a new method of optical analog-to-digital conversion based on oversampling and error diffusion coding that offers the potential to extend resolution and conversion rates beyond that currently possible with other electronic or optical converters.
