Two-Carrier Current Saturation in a Lateral Dmos

Two-Carrier Current Saturation in a Lateral Dmos

Conventional Ldmos transistors suffer from drain current "compression" in saturation (gm reduction). When the safe-operating area of the Ldmos is improved by suppressing the parasitic bipolar transistor, an unusual "expansion" in the drain characteristic emerges. This new device...

Zusammenfassung:Conventional Ldmos transistors suffer from drain current "compression" in saturation (gm reduction). When the safe-operating area of the Ldmos is improved by suppressing the parasitic bipolar transistor, an unusual "expansion" in the drain characteristic emerges. This new device behavior is described and a mechanism for the "expansion" proposed
