Hdl-a Modelling of Switched-current Delta Sigma A/d Converters

چکیده
Abstract: Switched Current (SI) is a very interesting analog technique to perform interface circuits in mixed analog/digital systems because it is compatible with a low cost digital CMOS process (single poly technologies). The attempt of this work is to shed some light on the SI delta-sigma converter design method making use of an analog Hardware Description Language. To demonstrate the performances of the HDL-A model to optimize delta-sigma converters, a first order SI delta-sigma modulator has been designed, simulated and implemented using a 0.7μm CMOS digital process. Also we have compared the simulated results and the experimental.

approved: Gabor C. Temes This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC c...

Analog to Digital converters plays an essential role in modern mixed signal circuit design. Mixed-signal System-on-chip devices such as Analog-to-Digital Converters (ADC) have become increasingly prevalent in the semiconductor industry. Nyquist Samplers require a complicated analog low pass filter to limit the maximum frequency input to the A/D and Sample and Hold circuit. Sigma-Delta (ΣΔ) modu...

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...

This thesis demonstrates that analog-to-digital (A/D) conversion at the intermediatefrequency stage of a radio is feasible for a wide range of cellular and cordless telephony standards. Placing the A/D converter as close as possible to the front end of the radio has manufacturing advantages and allows the use of sophisticated DSP algorithms which are especially usem with digitally coded transmi...

A simulation tool named SDSI, specifically suited for the simulation of switched-current (SI) sigma-delta data converters, has been developed in an interactive design environment. The tool exploits the sampled-data nature of the circuits and provides several levels of hierarchy for the models. High level behavioural models are suited for initial system-level simulations and specification of bui...
