  1. 6. Digitally Controlled Oscillator for mm-Wave Frequencies

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rikard Gannedahl; Johan Holmstedt; [2018]
    Keywords : RF; RFIC; oscillator; DCO; mm-wave; Technology and Engineering;

    Abstract : In the fifth generation of mobile communication, 5G, frequencies above 30 GHz, so-called millimeter-wave (mm-wave) frequencies are expected to play a prominent role. For the synthesis of these frequencies, the all-digital phase locked loop (ADPLL) has recently gained much attention. READ MORE

  3. 7. 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. 8. 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. 9. A Continuous-Time ADC and DSP for Smart Dust

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Dhurv Chhetri; Venkata Narasimha Manyam; [2011]
    Keywords : smart dust; Event-driven ED ; continuous time CT ; Delta-modulation DM ; segmented register string Digital to analog converter DAC ; digital signal processing DSP ;

    Abstract : Recently, smart dust or wireless sensor networks are gaining more attention.These autonomous, ultra-low power sensor-based electronic devices sense and process burst-type environmental variations and pass the data from one node (mote) to another in an ad-hoc network. READ MORE

  6. 10. 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
