High Speed Delay-Locked Loop for Multiple Clock Phase Generation
In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...
متن کاملA low-phase-noise 18 GHz Kerr frequency microcomb phase-locked over 65 THz
Laser frequency combs are coherent light sources that simultaneously provide pristine frequency spacings for precision metrology and the fundamental basis for ultrafast and attosecond sciences. Recently, nonlinear parametric conversion in high-Q microresonators has been suggested as an alternative platform for optical frequency combs, though almost all in 100 GHz frequencies or more. Here we re...
متن کاملTuning extension of a Difference-Frequency generation up to 100 nm using V-shaped external-cavity for the pump laser
In this research, tunability of a commercial diode laser has extended to about more than ± 11 nm using a V-shaped external-cavity fabricated around the laser. Although under normal condition it can be tuned up to about ± 4 nm just by changing its temperature and injection current. Such modified diode laser has then used in a difference-frequency generation (DFG) experimental setup as pump sourc...

متن کاملProgrammable Frequency Divider Design for Multi – Ghz Phase Locked Loop (PLL) System
The objective of this project is to develop a Programmable Frequency divider design for multi GHz PLL System implementation on FPGA using VHDL (hardware description language). The frequency divider architecture features 6 parallel divider chains, each one of them implementing a single division ratio. The desired frequency division ratio is then selected using the four control bits of an output ...
