TL;DR: The V5 ultraviolet auroral imager is one of a complement of experiments launched into polar orbit aboard the Swedish spacecraft Viking in February of 1986 as mentioned in this paper, which consists of two intensified wide-angle f/1 cameras, identical except in passband, with electronic despinning providing exposure times of one second.

TL;DR: Noise figure optimization techniques for inductively degenerated cascode CMOS low-noise amplifiers (LNAs) with on-chip gate inductors are discussed, and three of the power matched techniques significantly improve the noise figures for LNA designs that are to employ on- chip gate inducters.

TL;DR: The noise figure of the presented LNA is to the authors' knowledge the lowest noise figure achieved by a power matched wideband CMOS LNA at room temperature.

Abstract: In this article, the large-signal, small-signal, and noise performance of the Cherry-Hooper amplifier with emitter-follower feedback are analyzed from a design perspective. A method for choosing the component values to obtain a low group delay distortion or Bessel transfer function is given. The design theory is illustrated with an implementation of the circuit in a 47-GHz SiGe process. The amplifier has 19.7-dB gain, 13.7-GHz bandwidth, and /spl plusmn/10-ps group delay distortion. The amplifier core consumes 34 mW from a -3.3-V supply.

TL;DR: In this article, a subsurface signal transmitting apparatus including an insulation coupler, a carrier device, and a by-pass system for avoiding pressure build-up either above or below the apparatus is presented.
