  1. 1. Design of a 16 GSps RF Sampling Resistive DAC with on-chip Voltage Regulator

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Pontus Thomsson; Cyrus Seyed Aghamiri; [2021]
    Keywords : DAC; LDO; RDAC; 16GSps; 12-bit; Digital-to-Analog Converter; Low-Dropout Regulator;

    Abstract : Wireless communication technologies continue to evolve to meet the demand for increased data throughput. To achieve higher data throughput one approach is to increase the bandwidth. One problem related to very large bandwidths is the implementation of digital-to-analog converters with sampling rates roughly in the 5 to 20 GHz range. READ MORE

  3. 2. Design of a Rom-Less Direct Digital Frequency Synthesizer in 65nm CMOS Technology

    University essay from Elektroniska komponenter; Tekniska högskolan

    Author : Golnaz Ebrahimi Mehr; [2013]
    Keywords : Rom-Less DDFS; Current Steering Digital-to-Analog Converter; Interleaved DACs; Return-to-Zero; Sine weighted DAC;

    Abstract : A 4 bit, Rom-Less Direct Digital Frequency Synthesizer (DDFS) is designed in 65nm CMOS technology. Interleaving with Return-to-Zero (RTZ) technique is used to increase the output bandwidth and synthesized frequencies. The performance of the designed synthesizer is evaluated using Cadence Virtuoso design tool. With 3. READ MORE

  4. 3. Design of Pipelined Analog-to-Digital Converter with SI Technique in 65 nm CMOS Technology

    University essay from Elektroniksystem

    Author : Dinesh Babu Rajendran; [2011]
    Keywords : Pipelined Analog-to-Digital Converter; Sample and Hold Amplifier; Comparator; Current-Steering Digital-to-Analog Converter; Binary to Thermometer Decoder;

    Abstract : Analog-to-digital converter (ADC) plays an important role in mixed signal processingsystems. It serves as an interface between analog and digital signal processingsystems. In the last two decades, circuits implemented in current-modetechnique have drawn lots of interest for sensory systems and integrated circuits. READ MORE

  5. 4. 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

  6. 5. Digital-To-Analog Converter for FSK

    University essay from Institutionen för systemteknik

    Author : Athfal Salim J; [2007]
    Keywords : DAC; FSK; 10-bit; layout; 130 nm; Digital-To-Analog; CMOS; Common centroid;

    Abstract : This thesis is one part of a overall task of designing a module for frequency shift keying (FSK) to be used in an Ultra Wide Band (UWB) system. The FSK system has a Direct Digital Synthesizer (DDS) and Digital-to-Analog (DAC). The DACs differential current signals are directly fed to a RF (Radio Frequency) unit that generates the UWB RF signal. READ MORE
