A Digital Implementation of a Frequency Steered Phase Locked Loop
A digital implementation of a new technique that delivers an extremely accurate and stable phase locked loop system (PLL) is presented. The new technique uses competing phase and frequency loops to incorporate an accurate local reference frequency into the phase locked loop structure. Disturbances on the phase loop caused by the digital frequency loop are identified and a method to mitigate the...
متن کاملA Frequency Synthesis of All Digital Phase Locked Loop
All Digital Phase locked loops (ADPLL) plays a major role in System on Chips (SoC). Many EDA tools are used to design such complicated ADPLLs. It operates on two modes such as frequency acquisition mode and phase acquisition mode. Frequency acquisition mode is faster compared to Phase acquisition, hence frequency synthesis is performed. The CMOS technology is used to design such a complex desig...
متن کاملPhase Frequency Detector Using Transmission Gates for High Speed Applications
In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
متن کاملFast Frequency Acquisition Phase Frequency Detector with Minimal Dead Zone for High Frequency Phase Lock Loop
This paper introduces a new-type Phase-Frequency Detector (PFD) for Charge-Pump based Phase-Looked-loops (CPPLLs). Dead zone in a phase-frequency detector reduces the input detection range and make worse cycle slips. This brief analyzes the blind zone in latch-based PFDs and proposes a technique that removes the blind zone caused by the pre-charge time of the internal nodes. With the proposed t...
متن کاملDesign of a Phase Locked Loop as a Frequency Multiplier Using Self Healing Circuit
High performance digital systems use clocks to sequence operations and synchronize between functional units and between ICs. The circuit performance are degraded by some factors such as variability, leakage and improper matching in the device. when this particular PLL is made in the CMOS technology, it will lead to some leakage and variability. This paper proposes the PLL design as a frequency ...
