  1. 1. Area Efficient ADC for Low Frequency Application

    University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska högskolan

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

    Abstract : 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. READ MORE

  3. 2. 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. 3. Realization of Cascade of Resonators with Distributed Feed-Back Sigma-Delta

    University essay from Institutionen för systemteknik

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

    Abstract : 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. READ MORE

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

    University essay from Elektroniksystem

    Author : Anders Johansson; [2009]
    Keywords : CMOS process; Scaling; Operational transconductance amplifier; Optimization tool;

    Abstract : 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. READ MORE
