  1. 11. 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

  3. 12. 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

  4. 13. Design and Implementation of a Direct Digital Frequency Synthesizer using Sum of Weighted Bit Products

    University essay from Institutionen för systemteknik

    Author : Abdul Majid; Abdul Waheed Malik; [2009]
    Keywords : Digital Frequency Synthesizer; Current Steering DAC; Digital to Analog Converter.;

    Abstract : Direct Digital Frequency Synthesis (DDFS) is a method of producing an analog waveform by generating a time-varying signal in digital form, succeeded by digital-to-analog reconstruction. At behavioral level the bit products with specified weights are used to generate the sine wave. READ MORE

  5. 14. Pulse And Noise shaping D/A converter (PANDA) – Block implementation in 65nm SOI CMOS

    University essay from Elektroniksystem; Institutionen för systemteknik

    Author : Joel Hägglund; [2009]
    Keywords : 100GET; CMOS; DAC; interleaving; PANDA; SIAM; SOI;

    Abstract : In the European research projects SIAM and 100GET, building blocks for 100Gbit Ethernet optical link have been implemented. Data are sent from a computer, modulated, converted to analog, mixed onto the RF-band, sent through an optical link, down-mixed, converted back to digital, demodulated and sent to a receiving computer.

  6. 15. Reduction of Simultaneous Switching Noise in Analog Signal Band on a Chip

    University essay from Institutionen för systemteknik

    Author : Syed Muhammad Yasser Sherazi; Shahzad Asif; [2008]
    Keywords : CMOS; DCVSL; PRBS; ROM; TSPCL; Implementation on Chip; Noise Reduction; Substrate noise; Simultaneously;

    Abstract : In the era of VLSI the technological advancements have lead us to integrate not only digital circuits of high device density but both digital and analog circuits on to the same chip. In recent years the number of devices on a chip has spectacularly increased, all because of the downward scaling in sizes of the devices. READ MORE
