Phase noise and the Y-factor noise figurePete Hanish
摘要: A noise figure below 3 dB was obtained for the first time in a CW pumped PSA based on a PPLN waveguide. The 40 Gbit/s-DPSK receiver sensitivity was improved by using the PSA as a preamplifier.关键词: lithium compounds optical pumping optical receivers optical waveguides phase shift ...
(3). If the carrier frequency ωcx is high enough, the first three components are separable in the Fourier domain, while the noise usually permeates the entire domain. The FT technique selects the spectrum of the second component, shifts it to the origin, and then inverse transforms it to...
Plot the phase noise analysis results in a figure, specified as on or off. Set PlotOption to 'on' to view the power spectrum and phase noise profile plots. If the Name-Value pair argument 'Type' is specified as 'Time', you can only plot the phase noise profile of the time-domain si...
We show how the location and lateral extent of the associated seismic source is period- and phase-dependent. This information is crucial for the use of body waves for ambient noise imaging and gives insights about the sea state, complementary to satellite data....
The thesis considers the design and optimization of oscillators targeting low phase noise, given boundary conditions from the technology. Crucial technology figures are power capability, RF noise figure, low-frequency noise and the quali... Mikael Horberg 被引量: 1发表: 2017年 HIGH FREQUENCY CIRCUIT...
Using the procedure described above, the measured amplifier phase noise is subtracted from the measured DUT phase noise to obtain the precise DUT phase noise. Again, it is important that the gain and noise figure of the amplifiers resemble one another as closely as possible. Note that a DUT ...
It aims at defining a benchmark figure-of-merit (FOM) that is compatible with the well-known FOM for oscillators but now extended to an entire PLL. The phase noise that is generated by the thermal noise in the oscillator and loop components is calculated. The power dissipation is estimated...
This example shows how to predict the phase noise at the output of a phase-locked loop (PLL), simulate the PLL using the PLL Testbench, and compare the simulation results to theoretical predictions.
