  1. 1. Area Efficient ADC for Low Frequency Application

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska högskolan

    Författare :Abdul Wahab Sami; [2014]
    Nyckelord :Cyclic ADC; Sample and Hold; Multiply-By-Two-Amplifier; Bottom Plate Sampling; OTA; Area; Low power.;

    Sammanfattning : Analog to digital converters (ADCs) are the fundamental building blocks in communication systems. The need to design ADCs, which are area and/or power efficient, has been common. Various ADC architectures, constrained by resolution capabilities, can be used for this purpose. LÄS MER

  3. 2. A Study on the Design of Reconfigurable ADCs

    Master-uppsats, Elektroniksystem; Tekniska högskolan

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

    Sammanfattning : 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. LÄS MER

  4. 3. Realization of Cascade of Resonators with Distributed Feed-Back Sigma-Delta

    Master-uppsats, Institutionen för systemteknik

    Författare :Jawad Saleem; Abdul Mateen Malik; [2009]
    Nyckelord :sigma-delta modulator; operational transconductance amplfier; analog to digital converter; digital to analog converter; signal flow graph;

    Sammanfattning : The Sigma Delta Modulator (SDM) based analog to digital conversion is cost effective and have the advantages as higher reliability, increased functionality, and reduction in chip cost. The thesis work includes the modeling of SDM with the signal flow graph in Matlab, optimization of the coefficients to improve the noise transfer function and signal transfer function. LÄS MER

  5. 4. Evaluation of different CMOS processes using a circuit optimization tool

    Uppsats för yrkesexamina på grundnivå, Elektroniksystem

    Författare :Anders Johansson; [2009]
    Nyckelord :CMOS process; Scaling; Operational transconductance amplifier; Optimization tool;

    Sammanfattning : The geometry of CMOS processes has decreased in a steady pace over the years at the same time as the complexity has increased. Even if there are more requirements on the designer today, the main goal is still the same: to minimize the occupied area and power dissipation. LÄS MER

  7. 5. Implementation of a Simulated Annealing algorithm for Matlab

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Stephane Moins; [2002]
    Nyckelord :Electronics; Simulated annealing; Matlab; circuit optimization; analog circuits; Elektronik;

    Sammanfattning : In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. LÄS MER
