    Keywords : RF sampling; Sampling Mixer; Downconversion; Sigma Delta modulator; Low pass Sigma Delta ADC; Passive Sigma Delta ADC; Mixer inside the loop;

    Abstract : In today’s world the multi-standard wireless receivers are gaining more and more popularity. End-users want to access voice, data and streaming media from a single wireless terminal. An ideal approach for multi-standard receiver front-end is to digitize a wide band RF signal available from the antenna. READ MORE

  4. 34. Design and Evaluation of an Ultra-Low Power Successive Approximation ADC

    University essay from Institutionen för systemteknik

    Author : Dai Zhang; [2009]
    Keywords : Analog-to-digital converter ADC ; charge redistribution; CMOS; low power; low supply voltage; successive approximation; latched comparator;

    Abstract : Analog-to-digital converters (ADC) targeted for use in medical implant devices serve an important role as the interface between analog signal and digital processing system. Usually, low power consumption is required for a long battery lifetime. READ MORE

  5. 35. Analysis of noise and offset in the comparator of ananalog-to-digital converter

    University essay from Institutionen för systemteknik

    Author : Annie Rydholm; [2008]
    Keywords : Analog-to-digital conversion; comparator; offset; noise;

    Abstract : Since digital system has become very common today it is important to have good interfaces in between the analog and digital domain. This puts high demandson the analog to digital converter. It is therefore important in the design of theanalog to digital converter to reduce noise and offset as much as possible. READ MORE
