   Sammanfattning : Today there exist several applications where a real visible scene needs to be sampled to electrical signals, e.g., video cameras, digital still cameras, and machine vision systems. LÄS MER

3. 37. Low Noise Oscillator in ADPLL toward Direct-to-RF All-digital Polar Transmitter

   Författare :Jian Chen; Li-Rong Zheng; Fredrik Jonsson; Hannu Tenhunen; Georges Gielen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; all-digital; digitally-intensive; frequency modualtion; phase modulation; amplitude modulation; polar; transmitter; oscillator; digital controled oscillator; DCO; VCO; voltage controled oscillator; class-C oscillator; class-D PA; ADPLL; phase noise; RF; CMOS.;

   Sammanfattning : In recent years all-digital or digitally-intensive RF transmitters (TX) have attracted great attention in both literature and industry. The motivation is to implement RF circuits in a manner suiting advanced nanometer CMOS processes. To achieve that, information is encoded in the time-domain rather than voltage amplitude. LÄS MER

4. 38. Implementation of digit-serial filters

5. 39. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic

   Författare :Peter Nilsson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Chip Clocking; Digital IF-Filtering; Digital Wideband Filtering; Elektronik; Electronics; Bit-Serial Arithmetic; CMOS; Custom DSP; VLSI;

   Sammanfattning : This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. LÄS MER

7. 40. Low-frequency noise in high-k gate stacks with interfacial layer engineering

   Författare :Maryam Olyaei; Bengt Gunnar Malm; Paolo Pavan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; high k; 1 f noise; low-frequency noise; number fluctuations; mobility fluctuat ions; traps; interfacial layer; TmSiO; Tm 2O3; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The rapid progress of complementary-metal-oxide-semiconductor (CMOS) integrated circuit technology became feasible through continuous device scaling. The implementation of high-k/metal gates had a significantcontribution to this progress during the last decade. However, there are still challenges regarding the reliability of these devices. LÄS MER
