WebMar 19, 2015 · The Shockley diode equation doesn't distinguish between carrier ($T_{eh}$) and lattice temperature $T$; it assumes that they are in equilibrium, $T_{eh} = T$. WebThe dynamic resistance is used to get the volt drop over the small signal ac resistance. They give the equation. (1) I = I s ( e e V / k T − 1) where I is the diode current, V is the diode voltage, k is Boltzmann's constant, T is the temperature in Kelvin, and I s is the reverse leakage current. They then derive the dynamic resistance as d V ...
