Comparison of Hot Electron and Related Amplifiers
1962 International Electron Devices Meeting, 1962It is proposed that novel amplifiers be compared with each other and with existing amplifiers on the basis of as many figures of merit as are calculable. The bipolar transistor; field-effect transistor; Schottky-emitter, space-charge-limited-emitter, and tunnel-emitter, metal-base, hot-electron amplifiers are compared with respect to frequency cutoff ...

Transferred Electron Amplifiers and Oscillators
IEEE Transactions on Microwave Theory and Techniques, 1970The current status of transferred electron devices (TEDs) is surveyed. The physics of the transferred electron effect, the theory of amplifiers and oscillators, material growth, device fabrication, and the design of amplifier and oscillator circuits are discussed along with a presentation of the outlook for the near future.

Measurement Techniques, 1966
Up-to-date electrometer tube amplifiers are a perfect equipment for measuring currents and voltages from sources with a large internal resistance, and they can be used for solving a wide range of problems related to electrometric measurements. The current sensitivity of mass-produced tube electrometers amounts to 10−15−10−14 A.

Quasiballistic electronic transport in a tunneling hot-electron-transfer amplifier
Physical Review B, 1991Ce transport est simule en le traitant comme une diode a barriere double ou le champ a travers chaque barriere peut varier independemment. Le courant est evalue en calculant le coefficient de transmission de la structure entiere en partant d'un cadre de transport coherent, puis en introduisant une diffusion elastique et inelastique des electrons entre ...

A nondegenerate electron beam parametric amplifier
IRE Transactions on Electron Devices, 1961In a non-degenerate electron beam parametric amplifier (EBPA), signal and idler frequencies are far apart. This contrasts with the more familiar degenerate type which uses a pump frequency approximately equal to twice the signal frequency, thus placing the idler near the signal.

Phase variation in free-electron laser amplifiers
IEEE Journal of Quantum Electronics, 1987The evolution of the phase of the output radiation of free-electron laser amplifiers is investigated by means of a three-dimensional simulation code. The configuration employed consists of the propagation of a relativistic electron beam through a loss-free cylindrical waveguide in the presence of a helically symmetric wiggler and a uniform axial guide ...

Amplifiers before electronics — the Magnifiers
2008 IEEE History of Telecommunications Conference, 2008Amazing ingenuity was shown by dasiaelectricianspsila prior to the development of the thermionic valve (tube) into a reliable means of amplification of extremely low current signals in the earliest telecommunication systems. This paper classifies the devices used and then describes the principles involved in the group known as magnifiers.
