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

Since the existence of digital signal processing, A/D converters have been playing a very important role to interface analog and digital worlds. They perform the digitalization of analog signals at a fixed time period, which is generally specified by the application.

Mathematics of Analog‐to‐Digital Conversion
Communications on Pure and Applied Mathematics, 2012AbstractAs the performance of digital circuits and the capacity of digital communication channels have advanced steadily over the past decades, digital signals have replaced analog signals in nearly every technological application domain, offering robustness, ever increasing quality, and speed.

In this chapter we will look at the properties of analog-to-digital converters (ADC) and the limitations they introduce into sampled data. We will discuss the relationship between the resolution and the dynamic range of ADCs and end this chapter by simulating techniques for improving the dynamic range of ADCs by gain ranging and oversampling.

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.

Many of the communications systems addressed in this book begin with an analog signal or have an analog signal for the output. For example, a radio receiver accepts an analog signal from the antenna, processes it and outputs either an analog audio signal or digital data depending on the information being received. A radio transmitter, on the other hand,
