  1. 6. Ultra-Low Power Input Driver for High-ResolutionDiscrete-Time Σ∆ Modulator

    University essay from Elektroniska komponenter; Tekniska högskolan

    Author : Yumiao Zhang; [2013]
    Keywords : ;

    Abstract : This thesis presents the design of an input driver for ultra-low power sigmadelta modulator. High resolution Σ∆ ADCs are becoming more and more usefulin ultra-low power medical applications. Therefore, reducing supply voltage andpower starts a new chanllenges both at architecture as well as circuit performancelevel. READ MORE

  3. 7. Implementation of a Low-Cost Analog-to-Digital Converter for Audio Applications Using an FPGA

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Johan Hellman; [2013]
    Keywords : ADC; Sigma-Delta; FPGA; LVDS;

    Abstract : The aim of this master’s thesis is to implement an ADC (Analog-to-Digital Converter) foraudio applications using external components together with an FPGA (Field-ProgrammableGate Array). The focus is on making the ADC low-cost and it is desirable to achieve 16-bitresolution at 48 KS/s. READ MORE

  4. 8. Design and Implementation of a high-efficiency low-power analog-to-digital converter for high-speed transceivers

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Choudhry Jabbar Younis; [2012]
    Keywords : Analog front end; data rates; Analog to digital converter; track and hold; bootstrap; averaging; interpolation;

    Abstract : Modern communication systems require higher data rates which have increased thedemand for high speed transceivers. For a system to work efficiently, all blocks ofthat system should be fast. It can be seen that analog interfaces are the main bottleneckin whole system in terms of speed and power. READ MORE

  5. 9. High-Speed Hybrid Current mode Sigma-Delta Modulator

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Balakumaar Baskaran; Hari Shankar Elumalai; [2012]
    Keywords : Current mode Sigma Delta Modulator; Leslie-Singh Architecture; Switched Current Integrator; Folded Cascode Integrator; Current mode Flash ADC; High Speed Latched Comparator; Cascode Current Mirrors;

    Abstract : The majority of signals, that need to be processed, are analog, which are continuous and can take an infinite number of values at any time instant. Precision of the analog signals are limited due to influence of distortion which leads to the use of digital signals for better performance and cost. READ MORE

  6. 10. 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
