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. A Study and Design of High Performance Voltage-Controlled Oscillators in 65nm CMOS Technology

   Master-uppsats, Elektroniska komponenter; Tekniska högskolan

   Författare :Kamran Afghari; [2012]
   Nyckelord :QVCO; Power Consumption; Phase Noise; Tuning Voltage; Communication Transceivers;

   Sammanfattning : In recent years, oscillators are considered as inevitable blocks in many electronic systems. They are commonly used in digital circuits to provide clocking and in analog/RF circuits of communication transceivers to support frequency conversion. LÄS MER
