A 1-m W, 14-bit [sigma] [delta] A/D converter with 10-KHz conversion rate

Creator:

Gupta, Shivani

Resource Type:

Masters Thesis
A study of basic building blocks of analog-to-digital delta-sigma modulators

Creator:

Guo, Yuhua

Abstract:

In this thesis, a novel Direct-Charge-Transfer (DCT) integrator structure is proposed, which can settle much faster than regular switch-capacitor integrators. A new Spread-Spectrum Dynamic Element Matching (SS-DEM) algorithm is also introduced, which can effectively spread or shape the nonlinearity error of multi-bit DAC in the feedback path, thus improve the...

Masters Thesis
A survey on continuous-time modulators : theory, designs and implementations

Creator:

Gao, Xiaoran

Abstract:

Recently, delta-sigma modulation has become a widely applied technique for high-performance analog-to-digital conversion of narrow-band signals. Most of the early designs used discrete-time structure for good accuracy and good linearity. The transfer functions are independent of the clock frequency. However, high unity-gain bandwidths of the opamps are required to satisfy...

Masters Thesis
A wideband low-power continuous-time delta-sigma modulator for next generation wireless applications

Creator:

Chen, Xuefeng

Abstract:

Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are widely used in wireless transceivers. Recently, continuous-time (CT) ΔΣ ADCs gain growing interest in wireless applications for their lower power consumption and wider input bandwidth as compared with the discrete-time (DT) counterparts. In this thesis, a wideband low-power CT ΔΣ modulator for next generation...

Dissertation
Adaptive, wideband analog-to-digital conversion for convergent communication systems

Creator:

Batten, Robert D., 1973-

Abstract:

The exponential rate of advances in modern communication devices in the last several years have brought us higher levels of functionality and performance as well as reductions in physical size and power consumption. To continue this rate of advancement, next generation systems require wider bandwidth and higher resolution ADCs. Additionally,...

Dissertation
Architectural Solutions for Analog Imperfections in ΔΣ Analog-to-Digital Based Systems

Creator:

Zali Asl, Samira

Abstract:

For today’s ubiquitous portable devices, innovative integrated circuits with high performance yet very low power are necessary. As these devices are used to communicate and sense real world signals in the environment, analog-to-digital converters (ADC) and systems are the key interface circuits needed to digitize the sensed information and they...

Dissertation
Architecture design of multiplexed incremental analog-to-digital converters

Creator:

Zhang, Zhiqing

Abstract:

Analog-to-Digital Data Converters (ADCs) used in instrumentation and measurements often require high absolute accuracy, including excellent linearity and negligible dc offset. Incremental data converters (IDCs) provide a solution for such measurement applications. Since IDCs are essentially delta-sigma converters with reset operation before each conversion, they retain most of the advantages...

Masters Thesis
Automated synthesis of analog to digital conversion

Creator:

Weaver, Skyler

Abstract:

This thesis describes circuit architectures and techniques that facilitate the automatic synthesis and fabrication of analog-to-digital converters (ADCs). Since automated synthesis already exists for digital circuits and is part of the digital circuit design flow, this work demonstrates the feasibility of ADC synthesis with little or no modification to presently...

Dissertation
Automated verilog-to-layout synthesis of ADCs using custom analog cells

Creator:

Waters, Allen

Abstract:

A procedure for automating the design and layout of analog-to-digital converters (ADCs) is presented. This procedure makes use of the existing synthesis and place-and-route tools that are common in digital circuit design. A method for adding rudimentary analog cells to the standard library is described, allowing the designer to synthesize...

Dissertation
Design of a 1.8-V 14-bit [delta] - [sigma] A/D converter with 8X oversampling and 4 MHz Nyquist output rate

Creator:

Jiang, Ruoxin

Abstract:

In this dissertation, a new Δ∑ A/D converter is presented that is ideally suited for communication applications. It is based on a single-loop single-stage structure, which can realize a high maximum out-of-band quantization noise gain while maintaining stable operation and thus achieve 14-bit resolution at 8 times oversampling. A fifth-order...
