2. 1. Distributed Clocking and Clock Generation in Digital CMOS SoC ASICs

   Author : Thomas Olsson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; dual supply voltage; clock generator; digital; VHDL; CMOS; low-power; Distributed clocking; PLL;

   Abstract : With shrinking technologies and higher clock rates comes the possibility to transform multi chip implementations to a single System on Chip (SoC). Implementing clock distribution and limiting the power consumption becomes increasingly troublesome with increased clock rate and chip area. READ MORE

4. 2. Microwave CMOS Beamforming Transmitters

   Author : Johan Wernehag; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming transmitter; CMOS; frequency doubling power amplifier; polyphase filter; phase shifting;

   Abstract : The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes.

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

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

   Abstract : 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. READ MORE

6. 4. Low Noise Oscillator in ADPLL toward Direct-to-RF All-digital Polar Transmitter

   Author : Jian Chen; Li-Rong Zheng; Fredrik Jonsson; Hannu Tenhunen; Georges Gielen; KTH; []
   Keywords : 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.;

   Abstract : 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. READ MORE
