diode noise source
1Noise-figure meter — A noise figure meter is an instrument for measuring the noise figure of an amplifier, mixer, or similar device. An example instrument is the 1983 era Agilent 8970A. Contents 1 Measurement methods 2 Noise source 2.1 Thermal noise …
2Noise (electronics) — Electronic noise [1] is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is… …
3Noise generator — A Noise generator is a piece of equipment used to produce random electrical noise, in order to test how electrical equipment may react to noise, or to measure the intensity of noise. Tube noise generators were used for true random number… …
4Diode logic — (DL) or diode resistor logic constructs Boolean logic gates from diodes acting as electrically operated switches. While diode logic has the advantage of simplicity, the lack of an amplifying stage in each gate limits its application. Not all… …
5Diode bridge — Three bridge rectifiers. The size is generally related to the current handling capability …
6Diode — Figure 1: Closeup of a diode, showing the square shaped semiconductor crystal (black object on left) …
7Shot noise — Photon noise simulation. Shot noise is a type of electronic noise that may be dominant when the finite number of particles that carry energy (such as electrons in an electronic circuit or photons in an optical device) is sufficiently small so… …
8Tunable diode laser absorption spectroscopy — (TDLAS) is a technique for measuring the concentration of certain species such as methane, water vapor and many more, in a gaseous mixture using tunable diode lasers and laser absorption spectrometry. The advantage of TDLAS over other techniques… …
9Light-emitting diode — LED redirects here. For other uses, see LED (disambiguation). Light emitting diode Red, pure green and blue LEDs of the 5mm diffused type Type Passive, optoelectronic Working principle Electr …
10Avalanche diode — An avalanche diode is a diode (usually made from silicon, but can be made from another semiconductor) that is designed to go through avalanche breakdown at a specified reverse bias voltage and conduct as a type of voltage reference.The Zener… …
