1. 1. Design of a 30 GHz PLL for use in Phased Arrays

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Byron Murphy; [2016]
   Nyckelord :pll; phase-locked loop; beamforming; vco; qvco; Technology and Engineering;

   Sammanfattning : This project includes the research and implementation of a high frequency phase-locked loop (30 GHz or more) for beamforming use in a phased antenna array. The phase-locked loop includes a quadrature voltagecontrolled oscillator with a 10% tuning range and 417 degrees of phase control with a 10 degree resolution, a current mode latch in the divide-bytwo configuration operates over the quadrature voltage-controlled oscillator’s tuning range while consuming less than 583 uA of current, Dtype flip flops in a divide-by-8 configuration, a phase-frequency detector, a charge-pump, and a loop filter.

3. 2. Design and Simulation of Miscellaneous Blocks of an All-Digital PLL for the 60 GHz Band

   Master-uppsats, Elektroniksystem; Tekniska högskolan

   Författare :Hadiyah Butt; Manjularani Padala; [2013]
   Nyckelord :ADPLL; PLL; DCO; TDC;

   Sammanfattning : A phase-locked loop commonly known as PLL is widely used in communication systems. A PLL is used in radio, telecommunications, modulation and demodulation. It can be used for clock generation, clock recovery from data signals, clock distribution and as a frequency synthesizer. Most electronic circuits encounter the problem of the clock skew. LÄS MER

4. 3. Realizing a 32-bit Normally-Off Microprocessor With State Retention Flip Flops Using Crystalline Oxide Semiconductor Technology

   Master-uppsats, Elektroniska komponenter; Tekniska högskolan

   Författare :Niclas Sjökvist; [2013]
   Nyckelord :Normally Off; Low Power; Microprocessor; Nonvolatile; Power Gating; State Retention; Flip Flop; CAAC; IGZO;

   Sammanfattning : Power consumption is one of the most important design factors in modern electronic design. With a large market increase in portable battery-operated devices and push for environmental focus, it is of interest for the industry to decrease the power consumption of modern chips as much as possible.

5. 4. A Continuous-Time ADC and DSP for Smart Dust

   Master-uppsats, Elektroniksystem; Tekniska högskolan

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

   Sammanfattning : 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. LÄS MER

7. 5. Implementation of Low Power, Wide Range ADPLL for Video Applications

   Master-uppsats, Elektroniksystem

   Författare :Abdul Raheem Qureshi; Haris Qazi; [2010]
   Nyckelord :PLL; Digital; Low Power; Wide Range;

   Sammanfattning : Phase locked loop (PLLs) are the keystone for the electronic as well as for the communication circuits. Without any exaggeration, PLLs are found almost in every electronic and communication devices. Countless research has been performed, for the modification and enhancement of the PLLs circuit. LÄS MER
