| Zusammenfassung: | Phys. Rev. Lett. 96, 133602 (2006) General quantum restrictions on the noise performance of linear transistor
amplifiers are used to identify the region in parameter space where the
quantum-limited performance is achievable and to construct a practical
procedure for approaching it experimentally using only the knowledge of
directly measurable quantities: the gain, (differential) conductance and the
output noise. A specific example of resonant barrier transistors is discussed. |
