2024年5月9日 · 一般来说， dBc 是相对于载波（Carrier）功率而言，在许多情况下，用来度量与载波功率的相对值，如用来度量干扰（同频干扰、互调干扰、交调干扰、带外干扰等）以及耦合、杂散等的相对量值。 在采用dBc的地方，原则上也可以使用dB替代。 d B u V = 90 + d B m + 10 ∗ l g ( R ) dBuV = 90 + dBm + 10 * lg (R) dBuV = 90 +dBm+ 10∗lg(R),R为电阻值。 在PHS系统中正确应该是. d B m = d B u v − 107 dBm=dBuv-107 dBm = dBuv −107，因为其天馈阻抗为50欧 …

Abstract: This paper presents a charge-sampling PLL (CSPLL), that demonstrates the best reported jitter-power FOM of -258.9 dB thanks to its high phase-detection gain and to the removal of the power-hungry buffer driving the phase detector. It also achieves -65 dBc of reference spur by both minimizing the modulated capacitance seen by the VCO ...

Upgrade Your Motorcycle's Audio with DBC’s 8" Audio Lowers and Tweeter Pod package. Crafted from durable NYB polymer, these lowers fit any 8" speaker and mount directly to OEM Harley Davidson crash bars. Get rid of those factory 6.5” speakers.

With a 100-MHz input sinewave reference, the prototype in 28-nm CMOS achieves an rms jitter of 78 fs integrated from 1 k to 100 MHz, a spur level of −92 dBc with an FOM of −258 dB. The total power consumption is 2.6 mW at 6 GHz and the active area is 0.2 mm2.
