Ultra low noise readout with traveling wave parametric amplifiers: The DARTWARS project
نویسندگان
چکیده
The DARTWARS project has the goal of developing high-performing innovative traveling wave parametric amplifiers with high gain, large bandwidth, saturation power, and nearly quantum-limited noise. target frequency region for its applications is 5–10 GHz, where expected noise temperature below 600 mK. development follows two different approaches, one based on Josephson junctions kinetic inductance superconductors. This contribution mainly focuses amplifier, presenting design, preliminary measurements test homogeneity arrays junctions.

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 کاملRaman-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 ...
