1. 1. 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

3. 2. Investigation of the chirp properties of DFB-EAM’s for high speed baseband and RoF transmission links

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Miguel Olmedo Iglesias; [2012]
   Keywords : ;

   Abstract : The ever increasing bandwidth demands driven by an explosion in the mobile device market calls for more and more optical and wireless convergence due to the ability of optical communication systems to transport larger amounts of information to longer distances. Optical modulators are in charge of performing the electrical-to-optical domain conversion, which place them as one of the critical components in optical communication systems. READ MORE
