Abstract
A 1-10GHz Wide Tuning Range Phase Locked Loop is proposed in this thesis. In the first part, previous architectures of wide tuning range VCOs are introduced. The tuning range of single varactor is limited, so the frequency tuning range of basic LC-VCO is also limited. Consequently, various wideband VCOs are implemented to increase the frequency tuning range. In the second part the architecture of 1-10GHz Wide Tuning Range VCO is proposed, the expected output frequency is 1-10GHz. The divider is implemented by series of 2/3 cells to achieve the wide division range of 64~1023. Finally the architectures of phase frequency detector and charge pump are introduced. The simulation results are included in the third part, the used process is TSMC 65 nm CMOS technology with 1.2V supply voltage.
