Continuous-Time Sigma-Delta A/D Converters

Generalized sigma-derivation on Banach algebras

Let $mathcal{A}$ be a Banach algebra and $mathcal{M}$ be a Banach $mathcal{A}$-bimodule. We say that a linear mapping $delta:mathcal{A} rightarrow mathcal{M}$ is a generalized $sigma$-derivation whenever there exists a $sigma$-derivation $d:mathcal{A} rightarrow mathcal{M}$ such that $delta(ab) = delta(a)sigma(b) + sigma(a)d(b)$, for all $a,b in mathcal{A}$. Giving some facts concerning general...

A Review on Continuous Time Sigma Delta Modulator

This paper presents review on system level design of continuous time sigma delta modulator. A continuous time approach offers high accuracy with respect to discrete time modulator. Unity gain frequency and power can be achieved by continuous time design. as the sigma delta modulators are mainly implemented as discrete time circuits , a continuous time approach provides significant advantages fo...

Time-Mode Signal Quantization for Use in Sigma-Delta Modulators

The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...
