Abstract :
A cryogenic model based on transverse field and temperature dependence for different scattering mechanisms that influence channel mobility is developed. The kink effect is shown in both SOI (body floating) and bulk (carrier freezeout) at cryogenic temperatures below 30 Kelvin. The negative conductance model based on both a 2-dimensional electric field and temperature effect in SOI body tie transistors is also developed and implemented in SPICE
