3. Current-voltage characteristic (电流-电压特性) Breakdown (反向击穿); Reverse bias (反向偏压); Forward bias (正向偏压) https://en.wikipedia.org/wiki/File:Diode_current_wiki.png 3.1 Breakdown (击穿) 在非常大的反向偏压下,超过峰值反向电压(PIV),会发生称为反向击穿的过程,这会导致电流大幅增加,...
p-n diode equationThe equation of p-n diode current-voltage (J-V) of an organic heterojunction (HJ) including a hole and electron buffer layer is derived, and its characteristics are numerically simulated based on a polaron-pair model Giebink et al. (Forrest, Phys. Rev. B 82; 1-12, ...
This calculator solves for any single missing value in the ideal diode I-V equation for a forward-biased PN-junction diode. Parameters are current, saturation current, voltage, temperature, and ideality factor.
This equation defines the diode voltage curve: vd=vR−(vR−vRM)exp(−(t−t1)/τrr), (17)where vRM=vR−iRM(R−Lτrr) is the maximum diode reverse voltage. If Lτrr≫R, which is a common condition for the reverse recovery test circuit, the block calculates the maximum ...
Thermal voltage, Vt, is defined by the equation Vt=Nk∗Tq Where: N is the emission coefficient. T is the diode temperature. For more information, see Diode Temperature. k is the Boltzmann constant. q is the elementary charge on an electron. Current-Voltage Equations These equations defin...
aIn the current-voltage region, current loop gain decreases and its bandwidth increases because its gain- and bandwidth-setting resistance (at the gate of ) decreases as diode starts to conduct, which is the same reason why voltage loop gain simultaneously increases, now that starts to short cir...
