   Nyckelord :Rom-Less DDFS; Current Steering Digital-to-Analog Converter; Interleaved DACs; Return-to-Zero; Sine weighted DAC;

   Sammanfattning : 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. LÄS MER

3. 2. Design and Implementation of a Direct Digital Frequency Synthesizer using Sum of Weighted Bit Products

   Master-uppsats, Institutionen för systemteknik

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

   Sammanfattning : 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. LÄS MER
