  1. 21. Measurement of Delta-Sigma Converter

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Xiyang Liu; [2011]
    Keywords : Delta-Sigma converter; SINAD; THD;

    Abstract : With today’s technology, digital signal processing plays a major role. It is used widely in many applications. Many applications require high resolution in measured data to achieve a perfect digital processing technology. The key to achieve high resolution in digital processing systems is analog-to-digital converters. READ MORE

  3. 22. System Analysis and Implementation of Delta-Sigma Modulator Topologies with Low Gain Amplifiers in 90nm CMOS

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

    Author : Bilal Shahzad; [2011]
    Keywords : ;

    Abstract : Data converters are one of the key components in many applications ranging from wireless communication to data acquisitions system, sensors, audio electronics, video display electronics and analog microcontrollers. All of these use some type of data converter to perform the task of signal processing/condition for example in RF transceivers the received analog signal after passing through filters is converted to digital signal for further processing.

  4. 23. 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. 24. 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. 25.  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
