  1. 11. Ultra low power Analog-to-Digital Converter for Biomedical Devices

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

    Author : Jinxin Song; [2011]
    Keywords : ;

    Abstract : The biomedical devices often operate only with a battery, e.g., blood glucose monitor, pacemaker. Therefore, it is desirable to fully utilize the energy without sacrificing the performance of the system. READ MORE

  3. 12. 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. 14. Low-power 8-bit Pipelined ADC with current mode Multiplying Digital-to-Analog Converter (MDAC)

    University essay from Institutionen för systemteknik

    Author : Khurram Shahzad; [2009]
    Keywords : ADC; Pipelined ADC; MDAC; ENOB; low-power; digital error-correction;

    Abstract : In order to convert the analog information in the digital domain, pipelined analog-to-digital converter (ADC) offers an optimum balance of resolution, speed, power consumption, size and design effort. In this thesis work we design and optimize a 8-bit pipelined ADC for low-power. The ADC has stage resolution of 1. READ MORE
