Research of Resistance Thermal Noise
Xiaoping Zhang · Ordnance Industry Automation · 2006
In the environment, which temperature was higher than thermodynamics zero degree, the faintness current pulse was produced by a large amount of movement electrons in the resistance; the resistance thermal noise was created after superimposing. The square voltage was used to describe thermal noise voltage in determination. The thermal noise of resistance could be overcome by reducing the physical temperature, choosing appropriate working frequency band low noise elements, etc.
