Temperature Compensated Internal LNA Noise Calibration Source

Room-Temperature CMOS LNA With Non-50 Signal-Source Impedance

This paper presents a wideband low-noise amplifier (LNA) designed to be used as the first stage of the receiver in the Square Kilometer Array radio telescope. The LNA design procedure and its layout features are discussed. The noise figure optimization procedure determines the signal-source resistance that results in reduced noise figure. When used in the radio telescope, the required signal-so...

A Precision Calibration Solid State Noise Source with smooth Spectrum

 Abstract—A Solid state calibration noise source for precision radio astronomy receivers has been designed built and tested. The Noise source has flat output noise spectrum, stability in time and frequency (smooth response), very low power dissipation, excellent power match...all on a very compact package that can easily be integrated with a radio astronomy receiver. The noise source has an in...

Temperature-compensated chemical reactions.

Circadian rhythms are daily oscillations in behaviors that persist in constant light/dark conditions with periods close to 24 h. A striking feature of these rhythms is that their periods remain fairly constant over a wide range of physiological temperatures, a feature called temperature compensation. Although circadian rhythms have been associated with periodic oscillations in mRNA and protein ...
