Raman-noise induced noise-figure limit for χ parametric amplifiers
The non-zero response time of the Kerr (χ) nonlinearity determines the quantum-limited noise figure of χ parametric amplifiers. This non-zero response time of the nonlinearity requires coupling of the parametric amplification process to a molecular-vibration phonon bath, causing the addition of excess noise through Raman gain or loss at temperatures above 0K. The effect of this excess noise on ...
متن کاملDesign of Baluns and Low Noise Amplifiers in Integrated Mixed - Signal Organic Substrates
ACKNOWLEDGEMENTS As an old Malayalam song goes, " Karmam cheyyuka nammude lakshyam,Karma phalam tharum Eeshvaranallo " (" Act, for it is man's duty to act, but seek not the results of the action, for that is God's will alone "). I'd like to thank the Almighty for all his blessings so far, and pray for his continued benevolence. It is with great gratitude that I thank Prof. Swaminathan, for guid...
متن کاملComparative study of Noise Figure for recent Ultra-Wideband 45-nm CMOS Low-Noise Amplifiers (LNAs)
At receiving front end, the low noise amplifier design, being the first building block to receive the signal puts a tremendous challenge on modern day radio frequency engineers to meet real world problems involving trade-off in design issues. In this paper the recent trends for noise figure are streamlined in concurrence to Ultra Wide Band (UWB) radio transmission spectrum. A comparative study ...
متن کاملRESIDUAL PM and AM NOISE MEASUREMENTS, NOISE FIGURE and JITTER CALCULATIONS of 100 GHz AMPLIFIERS
We report the first definitive PM and AM noise measurements at 100 GHz of indium phosphide (InP) amplifiers operating at 5 K, 77 K, and room temperature. Amplifier gain ranged from +7 dB to +30 dB, depending on input RF power levels and operating bias current and gate voltages. The measurement system, calibration procedure, and amplifier configuration are described along with strategies for red...
متن کاملRaman-noise-induced noise-figure limit for chi(3) parametric amplifiers.
The nonzero response time of the Kerr [chi(3)] nonlinearity determines the quantum-limited noise figure of chi(3) parametric amplifiers. This nonzero response time of the nonlinearity requires coupling of the parametric amplification process to a molecular-vibration phonon bath, causing the addition of excess noise through Raman gain or loss at temperatures above 0 K. The effect of this excess ...
