AC analysis of UMOSFET ACCUFET

摘要

In this paper, the structure of a power UMOSFET ACCUFET has been investigated. For a given device length when the number of trenches is increased transconductance increases as the cut off frequency does. The effect of such a design on the conductance of the device is investigated and demonstrated that the conductance of this device can be improved by as large as 600% at the gate and drain voltage of 10 volts.
