A Wide-band Low-Noise Transimpedance Preamp
A transimpedance ampli er with nominal performance of 355MHz bandwidth, 20.6k transresistance, total equivalent input current noise of 43.1nA rms, and power dissipation of 20.7mW is presented.
متن کاملUltra-low-noise, High-impedance Preamp for Cryogenic Detectors
Introduction: Certain liquid-helium-cooled semiconducting materials make the most sensitive radiation detectors for the far-infra-red region of the spectrum. A few examples are the InSb Putley-mode detector, the Ge photoconductor and the GaAs photoconductor. All three display high dynamic impedance, relatively large bandwidth and very little noise because of their low operating temperature. The...

Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet and temporarily stored on the user's computer (client) including the desktop. This study aims to design an online sales application based cloud computing technology to help the artisans Palembang songket and do not rule out the possibility for other small medium enterprises (SMEs) to manage asset...
متن کاملActive Noise Control in Propeller Aircraft
A noisy environment dominated by low frequency noise can often be improved through the use of active noise control. This situation arises naturally in propeller aircraft where the propellers induce periodic low frequency noise inside the cabin. The cabin noise is typically rather high, and the passenger flight comfort could be improved considerably if this level were significantly reduced. This...
متن کاملNoise Power Spectrum in PROPELLER MR Imaging.
The noise power spectrum (NPS), an index for noise evaluation, represents the frequency characteristics of image noise. We measured the NPS in PROPELLER (Periodically Rotated Overlapping ParallEL Lines with Enhanced Reconstruction) magnetic resonance (MR) imaging, a nonuniform data sampling technique, as an initial study for practical MR image evaluation using the NPS. The 2-dimensional (2D) NP...
