  1. 6. 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

  3. 7. 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

  4. 8.  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

  5. 9. Algorithms for Noise Shaping and Interleaving of Digital to Analog Converters

    University essay from Institutionen för systemteknik

    Author : Robert Kihlberg; [2008]
    Keywords : noise shaping;

    Abstract : This thesis investigates the possibilities of interleaving multiple Digital to Analog converters in a high speed environment. Algorithms for interleaving and noise shaping as well as filters are tailored for high frequency operation.In the first part of the thesis, algorithms are evaluated and models to simulate errors are created.

  6. 10. 1 GS/s, Low Power Flash, Analog to Digital Converter in 90nm CMOS Technology

    University essay from Institutionen för systemteknik

    Author : Syed Hassan Raza Naqvi; [2007]
    Keywords : ADC; Data Converters; Flash ADC; Flash ADC in 90nm;

    Abstract : The analog to digital converters is the key components in modern electronic systems. As the digital signal processing industry grows the ADC design becomes more and more challenging for researchers. In these days an ADC becomes a part of the system on chip instead of standalone circuit for data converters. READ MORE
