WebbExpert Answer. (1) Describe, based on your observations, the I-V curves of the Fairchild 2N3904 npn transistor. At approximately what collector-emitter voltage (VCE) does the transition from saturation to active region occur? (Q1) Does this match theoretical expectations? (2) Describe the necessary conditions operation in the active region in ... Webb10 nov. 2003 · These theoretical intercepts are 0.125 V lower than the classical values obtained from Shockley's theory. This difference is due to three factors: the variation of the diffusion voltage, the nonzero electric field at the boundaries of the depletion region, and the contribution of electrons and holes.

WebbGain is given theoretically for quantum-well wire lasers where electrons are confined one-dimensionally. Maximum gain is obtained for a quantum-well wire perpendicular to light propagation, due to anisotropy of the dipole moment. Although the density-of-states is infinite at subband edges, gain remains finite due to the intraband relaxation. Webb6 apr. 2024 · The value of gain for an isotropic antenna is equal to 1.0 , that is , a unit gain. Now for the Hertzian dipole, it has a gain of 1.64 , Converting this gain in the unit of decibel, we get. 10 × log ( p o w e r g a i n) ⇒ 10 × log ( 1.64) ⇒ 10 × 0.2148 ⇒ 2.148 d B. This is approximately equal to 2.15 d B .
