Some of the noise comes from the environment, but most of the noise is generated internally in the amplifiers. One source of amplifier noise is the shot noise that accompanies a flow of electric current. Another source is thermal noise, emitted by any resistor at any given temperature. ...
A general method for finding the Mean first passage time of go neral diffusion processes driven by shot noise is suggested.───对散粒噪音驱动的一般扩散过程作了系统分析,为求平均首通时间提出了一个一般化的方法。 英语使用场景 The shot noise and thermal noise with homodyne demodulation technique is...
BIPOLAR TRANSISTOR WITH REDUCED THERMAL AND SHOT NOISE LEVELThe invention relates to a bipolar transistor (100) having an emitter and a base zone (10, 11) in a semiconductor substrate (12). In order to simultaneously minimise the thermal noise and the shot noise, the invention proposes that ...
The meaning of SHOT EFFECT is random fluctuations in the number of thermions per second emitted from the filament of a valve (such as a vacuum tube) that give rise to sputtering or popping noises in the amplifier.
13. The impacts of beat noise, multi-access interference, shot noise and thermal noise in coherent OCDMA are studied in this paper. 本文研究了相干光码分多址系统中拍频噪声、多址干扰、散粒噪声和热噪声对系统性能的影响。 14. We wanted to foul before he took the shot and we definitely did th...
The thermal surface resistance at the nanotube-dielectric interface is found to be 1.5*108 K/W, which is consistent with measurements by other techniques. 展开 关键词: Practical, Theoretical or Mathematical, Experimental/ carbon nanotubes nanotube devices resistance thermometers shot noise thermal ...
The noise power spectral density of a thermal current between two macroscopic dielectric bodies held at different temperatures and connected only at a quantum point contact is calculated. Assuming the thermal energy is carried only by phonons, we model the quantum point contact as a mechanical link...

5.5.1.1.3 Nyquist–Johnson noise Thermal noise, also referred to as the Nyquist–Johnson noise, is linked to the fluctuation in the flow of electrons generated by the thermal agitation of the carriers (Brownian motion) of electric charges across the load resistor as a function of its temperatu...
the carriers are not constrained in this manner then the resultant thermal noise will dominate and the Shot Noise will not be“seen”.A physical system where this constraint holds is a pn junction.The passage of each carrier across the depletion region of the junction is a random event,and ...
