Re: FN-PLL: reduction of fractional spur- where to add dithe. The spur is from the close loop simulation. All the blocks of pll are modeled in Veriloga. When the fractional number is 0.5, the spur is about -50dB. When the fractional number is 0.25, the spur is about -30dB. What bothering me is that there is nothing ...

Self-Dithered Digital Delta-Sigma Modulators for Fractional-N PLL

Webb25 jan. 2013 · Dither Can Boost Sampled Data System Performance By At Least 10 dB. Applying dither techniques to high-speed ADCs and DACs can give engineers the extra throughput needed for intensive applications ... WebbEssentially, digital PLLs can be cate- gorized into two different classes: The original all-digital PLL (ADPLL) in Fig. 1(a) (often referred to as “phase-domain” [2] or divider-less … tagline of nirvana ion launch

Webb1 feb. 2024 · This proof-of-concept prototype in 65nm CMOS shows >40dB spur improvement and achieves a worst-case fractional spur of −62.5dBc at 1.83kHz frequency offset, lower than state-of-the-art PLLs applying dither approaches. WebbIn this paper, we propose a self-dithering ΔΣ fractional-N PLL that inhibits the limit cycle oscillation without the external dither generating circuit. The proposed circuit generates the dither from internal signals of PLL. We simulated … Webb1 sep. 2016 · Novel analysis is presented which show that bang-bang digital PLLs allow better phase noise and spur performance at lower power consumption, area and … tagline of mcdonald\u0027s
