1. 6. Design of an all-digital, reconfigurable sigma-deltamodulator

   University essay from Elektroniksystem; Tekniska högskolan

   Author : Syed Asmat Ali Shah; Sohaib Ayaz Qazi; [2012]
   Keywords : ;

   Abstract : This thesis presents a model of reconfigurable sigma-delta modulator. These modulators areintended for high speed digital Digital to Analog Converters. The modulators are intendedto reduce complexity of current steering DACs and also considered as a front end of dataconverters. READ MORE

3. 7. High-Speed Hybrid Current mode Sigma-Delta Modulator

   University essay from Elektroniksystem; Tekniska högskolan

   Author : Balakumaar Baskaran; Hari Shankar Elumalai; [2012]
   Keywords : Current mode Sigma Delta Modulator; Leslie-Singh Architecture; Switched Current Integrator; Folded Cascode Integrator; Current mode Flash ADC; High Speed Latched Comparator; Cascode Current Mirrors;

   Abstract : The majority of signals, that need to be processed, are analog, which are continuous and can take an infinite number of values at any time instant. Precision of the analog signals are limited due to influence of distortion which leads to the use of digital signals for better performance and cost. READ MORE

4. 8. A Study on the Design of Reconfigurable ADCs

   University essay from Elektroniksystem; Tekniska högskolan

   Author : Prakash Harikumar; Anu Kalidas Muralidharan Pillai; [2011]
   Keywords : ADC; Sigma-Delta; Delta-Sigma; MASH; Pipelined; Reconfigurable; MDAC; Loop filter; Switched-Capacitor; SNDR; Time-interleaved; Flash;

   Abstract : Analog-to-Digital Converters (ADCs) can be classified into two categories namely Nyquist-rate ADCs and OversampledADCs. Nyquist-rate ADCs can process very high bandwidths while Oversampling ADCs provide high resolution using coarse quantizers and support lower input signal bandwidths. READ MORE

5. 9. DIGITAL GAIN ERROR CORRECTION TECHNIQUE  FOR 8-BIT PIPELINE ADC

   University essay from Elektroniska komponenter

   Author : khalid javeed; [2010]
   Keywords : ADC; Pipelined; Error Correction; Inter-Stage Gain;

   Abstract : An analog-to-digital converter (ADC) is a link between the analog and digital domains and plays a vital role in modern mixed signal processing systems. There are several architectures, for example flash ADCs, pipeline ADCs, sigma delta ADCs,successive approximation (SAR) ADCs and time interleaved ADCs. READ MORE

6. 10.  A Wideband High Dynamic Range Continuous-Time Sigma-Delta ADC for Wireless Applications

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Ye Xu; [2010]
   Keywords : ;

   Abstract : In recent years, the research toward the development of high speed and high resolution analog-to-digital converters (ADCs) has been equally driven by the demand of high-speed wire line and wireless communication services. Delta-Sigma ADCs are widely used in wireless applications due to their oversampling and noise shaping characteristics. READ MORE
