Johnson noise is caused by the fluctuation of charges or polarizable molecules in lossy materials. Its magnitude can best be calculated by means of statistical mechanics, which tells us that each degree of freedom must have associated with it an energy of ½ kT. This leads to the usual expressions for Johnson noise, including the fact that the available thermal noise power, from a resistor, a lossy network, a lossy dielectric, or an antenna is always kTB. In the case of a resistor, network, or… Expand
Measuring noise in microwave metamaterials
Electromagnetic metamaterials are artificially constructed media composed of arrays of electrical circuits that can exhibit electric and magnetic characteristics unlike those of any conventionalExpand
The Nature of Noise
TLDR
It is argued that noise and randomness are not the same, and a new conception of noise is proposed: namely that noise is what can result from an extra-contextual signal. Expand
Measuring trapped noise in metamaterials
Metamaterials constructed from conductive elements are lossy, and the structures act as sources of noise, whose spectrum is modified by the resonant nature of the medium itself. Furthermore, insideExpand

TLDR
It is found that the ultimate limit on energy spent to process one bit of data estimated by the proposed model of a CMOS logic gate is equal to the famous Landauer limit. Expand
Remarks on the spectral properties of thermal noise
Abstract Some models of thermal noise as generated by electrical resistances are discussed, especially with respect to the corresponding correlation properties. A modified approach for the derivationExpand
Noise in metamaterials
Metamaterials made up of resonant elements containing lossy metallic conductors will invariably give rise to Johnson noise. A model based on nearest neighbor interaction of magnetically coupledExpand
Noise in Oscillators
Noise affects the behavior of oscillators in at least two important ways. During sustained oscillation, noise creates undesired perturbations or modulation in both the amplitude and the phase of theExpand
Sampling Circuits That Break the kT/C Thermal Noise Limit
TLDR
Several circuit-level techniques are described which are used to reduce or cancel thermal noise and break the so-called kT/C limit, providing a powerful, new degree of freedom in circuit design. Expand
Lossy metamaterials: No effective medium properties without noise
Lossy metamaterial elements act as sources of Johnson noise, making such materials inherently noisy. A coupled transmission line model capable of describing the effective medium properties,Expand
