Fast-locking all-digital phase-locked loop with digitally controlled oscillator tuning word estimating and presetting
Design of a fast-locking phase-locked loop (PLL) is one of the major challenges in today’s wireless communications. A recently reported digitally controlled oscillator (DCO)-based all-digital PLL (ADPLL) can achieve an ultrashort settling time of 10 ms. This study describes a new DCO tuning word (OTW) presetting technique for the ADPLL to further reduce its settling time. Estimating the require...
متن کاملAn Overview: RF Design of Fast Locking Digital Phase Locked Loop
Phase locked loop (PLL) is a control system that generates a signal having a fixed relation with the phase of a reference signal. This system responds to both frequency and phase of the input signals, automatically raising or lowering the frequency of a controlled oscillator until it is matched to the reference in both frequency and phase. The performance of PLL is primarily dependent on the lo...
متن کاملDesign of All Digital Phase Locked Loop (d-pll) with Fast Acquisition Time
A Digital PLL is designed with improved acquisition time and power efficiency. The implemented D-PLL can operate from 6.54MHz to 105MHz with a power dissipation of is 7.763μW (at 210MHz) with 1.2V supply voltage. The D-PLL is synthesized using cadence RTL compiler in 45nm CMOS process technology.
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 کاملAll-Digital Phase Locked Loop (ADPLL) -A Review
--The All-Digital Phase-Locked Loop (ADPLL) is digital electronic circuit that are used in modern electronic communication systems like frequency synthesizer, modulator/demodulator etc. This paper presents a review of various ADPLL techniques. The range of input frequency of ADPLL is 40 to 98 MHz; the output frequency may be up to 2.92 to 4 GHz range. The components of ADPLL such as phase detec...
