Low-noise and high-frequency clock generation core for VLSI CMOS integration
A new phase-lock loop architecture is proposed to be used as a low-noise and high-frequency clock generation core for VLSI CMOS integration. The novel PLL architecture includes two charge pumps and an active loop filter architecture to implement a dual capacitance multiplication effect, which allows for the implementation of very large loop filter capacitors with very small silicon area. This n...
متن کاملDesign of Low Phase Noise Low Power CMOS Phase Locked Loops
Phase locked loop (PLL) is one of the most critical devices in modern electronic systems. PLLs are widely used as clock generator or frequency synthesis in communication systems, computers, radio and other electronic applications. Phase noise represents the phase variations of a PLL output signal and is the most important characteristic of PLLs because it reflects the stability of PLL systems. ...

متن کاملDesign and Analysis of Low Power Phase Locked Loop Based Frequency Synthesizer using Cadence Tool
The CMOS PLL based Frequency Synthesizer is a vital role in Receiver front end Sub component. The main objective of this paper is to design a high frequency of oscillation, less phase noise and power efficient PLL. In general, the PLL contains PFD, Loop Filter, VCO and Frequency Divider. The VCO is a critical component in Phase Locked Loop for low power CMOS designs. Here the Source Coupled VCO...
